Included in the package are the switching regulator, inductor and input/output capacitors. No additional components are required to finish the design. The TPS8267x is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The MicroSiPTM DC/DC converter operates at a regulated 5.5-MHz switching frequency and enters the powersave mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the quiescent current to 17A (typ) during light load operation. For noise-sensitive applications, the device has PWM spread spectrum capability providing a lower noise regulated output, as well as low noise at the input. These features, combined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency. The TPS8267x is packaged in a compact (2.3mm x 2.9mm) and low profile (1.0mm) BGA package suitable for automated assembly by standard surface mount equipment. 250 100 90 VI = 3.6 V, VO = 1.8 V 225 80 DC/DC Converter VIN 2.3 V .. 4.8 V VIN SW GND FB VOUT 1.8 V @ 600mA CO CI ENABLE L EN MODE Efficiency - % TPS82671SIP 175 60 150 50 125 40 100 75 30 MODE SELECTION 200 Efficiency PFM/PWM Operation 70 Power Loss PFM/PWM Operation 20 Power Loss - mW * * * * * * * * * * * * 23 50 25 10 GND Figure 1.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Operation above 4.8V input voltage for extended periods may affect device reliability. All voltage values are with respect to network ground terminal. In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating temperature (TINT(max)), the maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package in the application (JA), as given by the following equation: TA(max)= TJ(max)-(JA X PD(max)). To achieve optimum performance, it is recommended to operate the device with a maximum internal temperature of 105C. The human body model is a 100-pF capacitor discharged through a 1.5-k resistor into each pin. The machine model is a 200-pF capacitor discharged directly into each pin.

The converter operates at a regulated 5.5MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load currents, the TPS8267x converter operates in power-save mode with pulse frequency modulation (PFM). The converter uses a unique frequency-locked ring-oscillating modulator to achieve best-in-class load and line response. One key advantage of the non-linear architecture is that there is no traditional feed-back loop. The loop response to change in VO is essentially instantaneous, which explains the transient response. Although this type of operation normally results in a switching frequency that varies with input voltage and load current, an internal frequency lock loop (FLL) holds the switching frequency constant over a large range of operating conditions. Combined with best-in-class load and line-transient response characteristics, the low quiescent current of the device (approximately 17A) helps to maintain high efficiency at light load while that current preserves a fast transient response for applications that require tight output regulation. The TPS8267x integrates an input current limit to protect the device against heavy load or short circuits and features an undervoltage lockout circuit to prevent the device from misoperation at low input voltages. Fully functional operation is permitted down to 2.1V input voltage. POWER-SAVE MODE If the load current decreases, the converter enters power-save mode automatically. During power-save mode, the converter operates in discontinuous current, (DCM) single-pulse PFM mode, which produces a low output ripple compared with other PFM architectures. When in power-save mode, the converter resumes its operation when the output voltage falls below the nominal voltage. The converter ramps up the output voltage with a minimum of one pulse and goes into power-save mode when the output voltage is within its regulation limits. The IC exits PFM mode and enters PWM mode when the output current can no longer be supported in PFM mode. As a consequence, the DC output voltage is typically positioned approximately 0.5% above the nominal output voltage. The transition between PFM and PWM is seamless. PFM Mode at Light Load PFM Ripple Nominal DC Output Voltage PWM Mode at Heavy Load Figure 40. Operation in PFM Mode and Transfer to PWM Mode MODE SELECTION The MODE pin selects the operating mode of the device. Connecting the MODE pin to GND enables the automatic PWM and power-save mode operation. The converter operates in regulated frequency PWM mode at moderate to heavy loads, and operates in PFM mode during light loads. This type of operation maintains high efficiency over a wide load current range. Pulling the MODE pin high forces the converter to operate in PWM mode even at light-load currents. The advantage is that the converter modulates its switching frequency according to a spread spectrum PWM modulation technique that allows simple filtering of the switching harmonics in noise-sensitive applications. In this mode, the efficiency is lower when compared to the power-save mode during light loads.

This type of operation allows efficient power management by adjusting the operation of the converter to the specific system requirements. SPREAD SPECTRUM, PWM FREQUENCY DITHERING The goal of spread spectrum architecture is to spread out the emitted RF energy over a larger frequency range so that any resulting electromagnetic interference (EMI) is similar to white noise. The end result is a spectrum that is continuous and lower in peak amplitude. Spread spectrum makes it easier to comply with EMI standards. It also makes it easier to comply with the power supply ripple requirements in cellular and non-cellular wireless applications. Radio receivers are typically susceptible to narrowband noise that is focused on specific frequencies. Switching regulators can be particularly troublesome in applications where electromagnetic interference (EMI) is a concern. Switching regulators operate on a cycle-by-cycle basis to transfer power to an output. In most cases, the frequency of operation is either fixed or regulated, based on the output load. This method of conversion creates large components of noise at the frequency of operation (fundamental) and multiples of the operating frequency (harmonics). The spread spectrum architecture varies the switching frequency by approximately 10% of the nominal switching frequency, thereby significantly reduces the peak radiated and conducting noise on both the input and output supplies. The frequency dithering scheme is modulated with a triangle profile and a modulation frequency fm. 0 dBV FENV,PEAK Dfc Dfc Non-modulated harmonic F1 Side-band harmonics window after modulation 0 dBVref B = 2 x fm x (1 + mf ) = 2 x ( Dfc + fm ) B = 2 x fm x (1 + mf ) = 2 x ( Dfc + fm ) Figure 41.

SOFT START The TPS8267x has an internal soft-start circuit that limits the in-rush current during start-up. This circuit limits input voltage drop when a battery or a high-impedance power source is connected to the input of the MicroSiPTM DC/DC converter. The soft-start system progressively increases the switching on-time from a minimum pulse-width of 35ns as a function of the output voltage. This mode of operation continues for approximately 100s after the enable. If the output voltage does not reach its target value within the soft-start time, the soft-start transitions to a second mode of operation. If the output voltage rises above approximately 0.5V, the converter increases the input current limit and thus enables the power supply to come up properly. The start-up time mainly depends on the capacitance present at the output node and the load current. ENABLE The TPS8267x device starts operation when EN is set high and starts up with the soft start as previously described. For proper operation, the EN pin must be terminated and must not be left floating. Pulling the EN pin low forces the device into shutdown. In this mode, all internal circuits are turned off and the VIN current reduces to the device leakage current, which is typically a few hundred nanoamps. The TPS8267x device can actively discharge the output capacitor when it turns off. The integrated discharge resistor has a typical resistance of 100 . The required time to ramp down the output voltage depends on the load current and the capacitance present at the output node.

For most applications, the input capacitor that is integrated into the TPS8267x should be sufficient. If the application exhibits a noisy or erratic switching frequency, experiment with additional input ceramic capacitance to find a remedy. The TPS8267x uses a tiny ceramic input capacitor. When a ceramic capacitor is combined with trace or cable inductance, such as from a wall adapter, a load step at the output can induce ringing at the VIN pin. This ringing can couple to the output and be mistaken as loop instability or can even damage the part. In this circumstance, additional "bulk" capacitance, such as electrolytic or tantalum, should be placed between the input of the converter and the power source lead to reduce ringing that can occur between the inductance of the power source leads and CI. OUTPUT CAPACITOR SELECTION The advanced, fast-response, voltage mode, control scheme of the TPS8267x allows the use of a tiny ceramic output capacitor (CO). For most applications, the output capacitor integrated in the TPS8267x is sufficient. At nominal load current, the device operates in PWM mode; the overall output voltage ripple is the sum of the voltage step that is caused by the output capacitor ESL and the ripple current that flows through the output capacitor impedance. At light loads, the output capacitor limits the output ripple voltage and provides holdup during large load transitions. The TPS8267x is designed as a Point-Of-Load (POL) regulator, to operate stand-alone without requiring any additional capacitance. Adding a 2.2F ceramic output capacitor (X7R or X5R dielectric) generally works from a converter stability point of view, but does not necessarily help to minimize the output ripple voltage. For best operation (i.e. optimum efficiency over the entire load current range, proper PFM/PWM auto transition), the TPS8267xSIP requires a minimum output ripple voltage in PFM mode. The typical output voltage ripple is ca. 1% of the nominal output voltage VO. The PFM pulses are time controlled resulting in a PFM output voltage ripple and PFM frequency that depends (first order) on the capacitance seen at the MicroSiPTM DC/DC converter's output. In applications requiring additional output bypass capacitors located close to the load, care should be taken to ensure proper operation. If the converter exhibits marginal stability or erratic switching frequency, experiment with additional low value series resistance (e.g. 50 to 100m) in the output path to find a remedy. Because the damping factor in the output path is directly related to several resistive parameters (e.g. inductor DCR, power-stage rDS(on), PWB DC resistance, load switches rDS(on) ...) that are temperature dependant, the converter small and large signal behavior must be checked over the input voltage range, load current range and temperature range. The easiest sanity test is to evaluate, directly at the converter's output, the following aspects: * * PFM/PWM efficiency PFM/PWM and forced PWM load transient response During the recovery time from a load transient, the output voltage can be monitored for settling time, overshoot or ringing that helps judge the converter's stability. Without any ringing, the loop has usually more than 45 of phase margin. 20 Submit Documentation Feedback Copyright (c) 2010-2012, Texas Instruments Incorporated Product Folder Link(s): TPS82670 TPS82671 TPS82672 TPS82673 TPS82674 TPS82675 TPS82676 TPS82677 TPS826711 TPS82670, TPS82671, TPS82672, TPS82673 TPS82674, TPS82675, TPS82676, TPS82677, TPS826711 www.ti.com SLVSAI0D - OCTOBER 2010 - REVISED APRIL 2012 LAYOUT CONSIDERATION In making the pad size for the SiP LGA balls, it is recommended that the layout use non-solder-mask defined (NSMD) land. With this method, the solder mask opening is made larger than the desired land area, and the opening size is defined by the copper pad width. Figure 43 shows the appropriate diameters for a MicroSiPTM layout. Copper Trace Width Solder Pad Width Solder Mask Opening Copper Trace Thickness Solder Mask Thickness M0200-01 Figure 43.

Wider trace widths reduce device stand off and affect reliability. Best reliability results are achieved when the PWB laminate glass transition temperature is above the operating the range of the intended application. Recommend solder paste is Type 3 or Type 4. For a PWB using a Ni/Au surface finish, the gold thickness should be less than 0.5mm to avoid a reduction in thermal fatigue performance. Solder mask thickness should be less than 20 m on top of the copper circuit pattern. For best solder stencil performance use laser cut stencils with electro polishing. Chemically etched stencils give inferior solder paste volume control. SURFACE MOUNT INFORMATION The TPS8267x MicroSiPTM DC/DC converter uses an open frame construction that is designed for a fully automated assembly process and that features a large surface area for pick and place operations. See the "Pick Area" in the package drawings. Package height and weight have been kept to a minimum thereby to allow the MicroSiPTM device to be handled similarly to a 0805 component.

To estimate the junction temperature, approximate the power dissipation within the TPS8267x by applying the typical efficiency stated in this datasheet to the desired output power; or, by taking a power measurement if you have an actual TPS8267x device and TPS82671EVM evaluation module. Then calculate the internal temperature rise of the TPS8267x above the surface of the printed circuit board by multiplying the TPS8267x power dissipation by the thermal resistance. The actual thermal resistance of the TPS8267x to the printed circuit board depends on the layout of the circuit board, but the thermal resistance given in the Thermal Information Table can be used as a guide. Three basic approaches for enhancing thermal performance are listed below: * Improve the power dissipation capability of the PCB design. * Improve the thermal coupling of the component to the PCB. * Introduce airflow into the system.
