DS50002656A-page 9 MIC2800 Evaluation Board User's Guide 1.2.2 MIC2800 Device Overview The MIC2800 device is a high-performance power management IC, giving three output voltages with maximum efficiency. Combining a 2 MHz DC/DC converter with an LDO regulator (LDO1), the MIC2800 gives two high-efficiency outputs (DC/DC and LDO1), combined with the flexibility of a third output, a 300 mA LDO (LDO2). The MIC2800 features a LOWQ mode, reducing the total current draw in this mode to less than 30 A. In LOWQ mode, the output noise of the DC to DC converter is 75 VRMS, significantly lower than other converters which use a PFM light load mode that can interfere with sensitive RF circuitry. The DC to DC converter uses small values of the inductor and capacitors to reduce board space, but still retains efficiencies over 90%, at load currents up to 600 mA. The MIC2800 is a Cap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost and it is available in fixed output voltages in the 16-pin 3 mm x 3 mm QFN lead-free package. FIGURE 1-1: 1.3 MIC2800 Typical Application Circuit. MIC2800 EVALUATION BOARD OVERVIEW The MIC2800 Evaluation Board has been developed to evaluate the capabilities of the MIC2800 multi-output (DC-DC and 2 x LDO) device. The board is populated with the MIC2800-G1JS device and it is set to the following voltages: * VOUT1 (DC-DC Buck converter): 1.8V * VOUT2 (LDO1): 1.25V * VOUT3 (LDO2): 3.3V The MIC2800-G1JS allows support of the SAMA5D2 family MPUs when operating off a 5V input rail. However, by populating the board with another MIC2800 IC voltage option, other power supply solutions can be demonstrated. The MIC2800 Evaluation Board features independent Enable connectors (EN1 and EN2). To disable the regulators, a jumper must be placed on J1 (to disable the DC/DC converter and LDO1) or to J2 (to disable LDO2). Since it is not recommended to leave EN pins floating, the MIC2800 Evaluation Board features 100 k pull-up resistors, so the default value when the board is powered is ON. DS50002656A-page 10 2017 Microchip Technology Inc. Product Overview The MIC2800 Evaluation Board also features a LOWQ pin to switch the functionality of the DC/DC converter. When the LOWQ is logic high (>1V), the DC/DC converter works in PWM mode (normal operation mode with 600 mA output current capability). When the LOWQ is logic low (<0.2V), the DC/DC converter stops switching, the output voltage is supplied by a low noise linear regulator and the quiescent current of the device is greatly reduced. In linear (LDO) mode, the DC/DC converter output can deliver 60 mA of current to the load from the LDO pin. The LOWQ mode also limits the output load of both LDO1 and LDO2 to 10 mA To check the status of the MIC2800 outputs, Power-on Reset Output is available with a pull-up to VIN or to VOUT3. Active low on this output indicates an undervoltage condition on either one of the three regulators. The board can be powered from 3.6V to 5.5V. This input voltage range is determined by the 3.3V LDO2 that has a dropout voltage of maxim 300 mV overtemperature. If another version of the MIC2800 is placed on the board, the minimum input voltage must comply to VOUTLDO2 + 300 mV. FIGURE 1-2: 2017 Microchip Technology Inc.

MIC2800 EVALUATION BOARD USER'S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The MIC2800 Evaluation Board can be powered from a wide voltage range, from 3.6V to 5.5V, making it compatible with 5V rails and USB power. 2.2 GETTING STARTED To power up the MIC2800 Evaluation Board, the following steps must be completed: 1. Connect an external supply between VIN and GND terminals. Pay attention to the polarity. 2. With the output of the power supply disabled, set its voltage to the desired input test voltage (3.6V VIN 5.5V). An ammeter may be placed between the input supply and the VIN terminals. Be sure to monitor the supply voltage at the VIN terminal, as the ammeter and/or power lead resistance can reduce the voltage supplied to the device. 3. Connect a load between either VOUT1 and GND, VOUT2 and GND, or VOUT3 and GND. The load can be either passive (resistive) or active (electronic load). Some electronic loads can sink the programmed current starting from very low output voltage levels during startup. For a more realistic startup behavior evaluation, a resistive load or constant resistance is recommended. An ammeter may be placed between the load and the output terminals. Ensure the output voltage is monitored at the VOUT1, VOUT2 and VOUT3 terminals. To obtain the best output voltage regulation measurement and low noise, please measure with a ground spring on the output capacitor, corresponding to the desired output. 4. The MIC2800 Enable Pins (EN1, EN2) have pull-up resistors to VIN. By default, the output voltage will be enabled when the input supply of >2.7V is applied. To disable the device, apply a voltage of 0V to the EN1, EN2 terminals (J1 and/or J2). 5. Power-on Reset (POR) test point is provided to monitor the POR function (J10). The power-on reset output will go high after all the output voltages have reached 96% of their nominal voltage and will go low as son as one of the output voltages go below 91% of its nominal voltage. The POR flag has programmable assertion delay set by the capacitor placed on CSET pin to ground. 6. The inductance associated with long wires between the power supply and the board input may cause voltage spikes at load stepping, start-up into heavy loads or hot wire plug conditions. If the spikes exceed 6V absolute maximum input voltage, the MIC2800 may fail. This behavior is prevented by C9 capacitor (100F Al-Electrolytic capacitor) by absorbing voltage spikes. 2017 Microchip Technology Inc. DS50002656A-page 13 MIC2800 Evaluation Board User's Guide VOUT2 LDO1 VOUT3 LDO2 VOUT1 BUCK POWER SUPPLY FIGURE 2-1: 2.3 MIC2800 Evaluation Board - Test Points Description. EVALUATION BOARD DESCRIPTION 2.3.1 Power-on Reset Pull-up Resistor The MIC2800 Evaluation Board offers the possibility of connecting the POR pin to either VIN or VOUT3 (LDO2, 3.3V) by using J4. This provides the flexibility for direct interfacing with 3.3V systems or directly to VIN when the 3.3V rail is disabled. 2.3.2 Power-on Reset Capacitor (C7) The MIC2800 has a programmable POR delay set by placing a capacitor on the CSET pin. This pin is a current source output that charges a capacitor that sets the delay time for the POR output, from low to high. The current source of 1.25 A charges a capacitor up from 0V. When the capacitor reaches 1.25V, the output of the POR is allowed to go high. The delay time in microseconds is equal to the CSET capacitor in picofarads (Equation 2-1). EQUATION 2-1: PORDelay uS = CSET pF 2.3.3 LOWQ Mode MIC2800 is 2 MHz 600 mA DC/DC converter with two integrated 300 mA LDOs. This design combines good overall efficiency with low output noise. However, the DC/DC converter is always switching in PWM mode. To reduce quiescent current in light-load conditions, the MIC2800 features a LOWQ pin. In this mode, the DC/DC converter is disabled and the output voltage is provided by a low noise linear regulator (LDO) capable of supplying 60 mA to the load. In this mode, the other linear regulators (LDO1 and LDO2) will also be internally limited to 10 mA. DS50002656A-page 14 2017 Microchip Technology Inc. Installation and Operation 2.3.4 Using Fixed and Adjustable Voltage Options The MIC2800 Evaluation Board is designed for both fixed and adjustable options. Resistors R1 and R2 are used for setting the output voltage of the adjustable option of the DC/DC converter: R1 is the top voltage divider resistor and R2 is the bottom voltage divider resistor. The feedback voltage is 0.8V (nominal) and the output voltage can be adjusted from 1V to 2V. Note that LDO1 is powered from the DC/DC converter's output, so in order for LDO1 to maintain good regulation, the DC/DC output voltage should be minimum VDCDC - VDO. 2.3.5 Output Noise and Ripple Measurements The MIC2800 Evaluation Board is populated with headers used for measuring output noise and ripple on both the DC/DC converter and the LDOs (J5, J8 and J9). Each connector is designed to probe the output signal using the local ground as reference. This is the proper way of measuring low-amplitude ripple signals because it eliminates any noise caused by long oscilloscope ground leads or ground plane noise. 2.3.6 Board Layout Considerations It is recommended that the connection between the GND pins of the MIC2800 and GND terminals of the input capacitors is kept on the TOP of the PCB and no vias should be placed between them. This will improve transient behavior and decrease noise. It is also recommended that the TOP GND plane should extend under the device for optimal noise performance. 2017 Microchip Technology Inc.
