Operating from a 3.0 to 5.5 VDC input, the YNL05S100xy converters are ideal choices for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is generally a requirement. The converters are available in individual output voltage versions, allowing coverage of the output voltage range from 0.9 to 3.3 VDC. Each version is capable of providing an extremely tight, highly regulated and trimmable output. The YNL05S100xy converters provide exceptional thermal performance, even in high temperature environments with no airflow. No derating is required up to 85 C, without airflow at natural convection. This performance is accomplished through the use of advanced circuitry, packaging, and processing techniques to achieve a design possessing ultra-high efficiency, excellent thermal management, and a very low-body profile. The low-body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with advanced power electronics and thermal design, results in a product with extremely high reliability.

In many applications, the inductance associated with the distribution from the power source to the input of the converter can affect the stability of the converter. The use of decoupling capacitors is recommended in order to ensure stability of the converter and reduce input ripple voltage. Internally, the converter has 52 F (low ESR ceramics) of input capacitance. In a typical application, low - ESR tantalum or POS capacitors will be sufficient to provide adequate ripple voltage filtering at the input of the converter. However, very low ESR ceramic capacitors 100 - 200 F are recommended at the input of the converter in order to minimize the input ripple voltage. They should be placed as close as possible to the input pins of the converter. The YNL05S100xy has been designed for stable operation with or without external capacitance. Low ESR ceramic capacitors placed as close as possible to the load (minimum 47 F) are recommended for improved transient performance and lower output voltage ripple. It is important to keep low resistance and low inductance PCB traces for connecting load to the output pins of the converter in order to maintain good load regulation. Fig. A shows the input voltage ripple for various output voltages using four 47 F input ceramic capacitors. The same plot is shown in Fig. B with one 470 F polymer capacitor (6TPB470M from Sanyo) in parallel with two 47 F ceramic capacitors at full load.

ON/OFF (Pin 1) The ON/OFF pin is used to turn the power converter on or off remotely via a system signal. There are two remote control options available, positive logic (standard option) and negative logic, with ON/OFF signal referenced to GND. The typical connections are shown in Fig. C.

To turn the converter on the ON/OFF pin should be at a logic low or left open, and to turn the converter off the ON/OFF pin should be at a logic high or connected to Vin. See the Electrical Specifications for logic high/low definitions. The positive logic version turns the converter on when the ON/OFF pin is at a logic high or left open, and turns the converter off when at a logic low or shorted to GND. 100 80 60 40 Vin=5.0V 20 Vin=3.3V The negative logic version turns the converter on when the ON/OFF pin is at logic low or left open, and turns the converter off when the ON/OFF pin is at a logic high or connected to Vin. 0 0 1 2 3 4 Vout [V] Fig. A: Input Voltage Ripple, CIN = 4x47 F ceramic, full load.

This device must be capable of: - sinking up to 1.2 mA at a low level voltage of 0.8 V - sourcing up to 0.25 mA at a high logic level of 2.3 - 5.5 V. When using open-collector (open-drain) transistor with a negative logic option, add a pull-up resistor (R*) to Vin as shown in Fig. C: - 20 K, if the minimum Vin is 4.5 V - 10 K, if the minimum Vin is 3.0 V - 5 K, if the undervoltage shutdown at 2.05 - 2.15 V is required. Remote Sense (Pin 2) The remote sense feature of the converter compensates for voltage drops occurring only between Vout pin (Pin 4) of the converter and the load. The SENSE (Pin 2) pin should be connected at the load or at the point where regulation is required (see Fig. D). There is no sense feature on the output GND return pin, where the solid ground plane should provide a low voltage drop. equal to the product of the nominal output voltage and the allowable output current for the given conditions. When using remote sense, the output voltage at the converter can be increased up to 0.5 V above the nominal rating in order to maintain the required voltage across the load. Therefore, the designer must, if necessary, decrease the maximum current (originally obtained from the derating curves) by the same percentage to ensure the converter's actual output power remains at or below the maximum allowable output power. Output Voltage Adjust/Trim (Pin 3) The output voltage can be adjusted up 10% or down 10% of its nominal output rating using an external resistor. The converter without Trim feature is also available; see the Part Numbering Scheme section for the ordering information. Vin Y-Series Converter (Top View) ON/OFF Y-Series Converter Rload TRIM R T-INCR SENSE (Top View) Rw ON/OFF Vout GND TRIM Fig. E: Configuration for increasing output voltage. Vin Rload To trim up the output voltage, refer to Fig. E. A trim resistor, RT-INCR, should be connected between TRIM pin (Pin 3) and GND pin (Pin 5) with value of: For VO-NOM 1.2 V, Rw Fig. D: Remote sense circuit configuration. The option without SENSE pin is available; see the Part Numbering Scheme section for the ordering information. However, if remote sensing is not required, the SENSE pin must be connected to the Vout pin (Pin 4) to ensure the converter will regulate at the specified output voltage. If these connections are not made, the converter will deliver an output voltage that is slightly higher than the specified value. Because the sense lead carries minimal current, large traces on the end-user board are not required. However, the sense trace should be located close to a ground plane to minimize system noise and ensure optimum performance. When utilizing the remote sense feature, care must be taken not to exceed the maximum allowable output power capability of the converter, which is MCD10188 Rev. 1.0, 21-Jun-10 Vout Vin GND Vin SENSE RTINCR 24.08 RINT (VO -REQ - VO -NOM) [k] For VO-NOM = 1.0 V and 0.9 V, RTINCR 21.07 RINT (VO -REQ - VO -NOM) [k] where, RTINCR Required value of trim-up resistor [k] VOREQ Desired (trimmed) output voltage [V] VONOM Nominal output voltage [V] RINT Internal series resistor according to Table 1 [k] Table 1: Internal series Resistors RINT V0-NOM [V] RINT [k] Page 6 of 23 3.3 2.5 2.0 1.8 1.5 1.2 1.0 0.9 59 78.7 100 100 100 59 30.1 5.11 www.power-one.com YNL05S100xy DC-DC Converter Family Data Sheet 3.0 to 5.5 VDC Input; 0.9 to 3.3 VDC @ 10 A Output Protection Features To trim down the output voltage (Fig. F), a trim resistor, RT-DECR, should be connected between the TRIM pin (Pin 3) and SENSE pin (Pin 2), with a value of: For VO-NOM 1.2 V, RTDECR (VO -REQ - 0.8) * 30.1 RINT (VO -NOM - VO -REQ) RTDECR Output Overcurrent Protection (OCP) [k] The converter is protected against overcurrent and short circuit conditions.

The maximum DC voltage between any two pins is Vin under all operating conditions. Therefore, the unit has ELV (extra low voltage) output; it meets SELV requirements under the condition that all input voltages are ELV. Characterization General Information [V] where, VTRIM Output voltage applied to TRIM pin (referenced to GND) [V] The trim equations for the converters with VO-NOM 1.2 V are industry standard; thus allowing easy second sourcing. MCD10188 Rev. 1.0, 21-Jun-10 The converter will shut down under an overtemperature condition to protect itself from overheating caused by operation outside the thermal derating curves, or operation in abnormal conditions such as system fan failure. After the converter has cooled to a safe operating temperature, it will automatically restart. The converter is not internally fused. To comply with safety agencies' requirements, a recognized fuse with a maximum rating of 20 Amps must be used in series with the input line. For VO-NOM = 1.0 V, 0.9 V, VTRIM 0.7 Input undervoltage lockout is standard with this converter. The converter will shut down when the input voltage drops below a pre-determined voltage; it will start automatically when Vin returns to a specified range. The input voltage must be typically 2.05 V for the converter to turn on. Once the converter has been turned on, it will shut off when the input voltage drops below typically 1.9 V.

For example, Fig. x.1 will refer to the vertical thermal derating for all the output voltages in general. temperature was varied between 25 C and 85 C, with airflow rates from 30 to 500 LFM (0.15 m/s to 2.5 m/s), and vertical and horizontal mountings. The airflow during the testing is parallel to the short axis of the converter, going from pin 1 and pin 6 to pins 2-5. The following pages contain specific plots or waveforms associated with the converter. Additional comments for specific data are provided below. For each set of conditions, the maximum load current is defined as the lowest of: Test Conditions All data presented were taken with the converter soldered to a test board, specifically a 0.060" thick printed wiring board (PWB) with four layers. The top and bottom layers were not metalized. The two inner layers, comprised of two-ounce copper, were used to provide traces for connectivity to the converter. The lack of metalization on the outer layers as well as the limited thermal connection ensured that heat transfer from the converter to the PWB was minimized. This provides a worst-case but consistent scenario for thermal derating purposes. All measurements requiring airflow were made in the vertical and horizontal wind tunnels using Infrared (IR) thermography and thermocouples for thermometry. Ensuring components on the converter do not exceed their ratings is important to maintaining high reliability. If one anticipates operating the converter at or close to the maximum loads specified in the derating curves, it is prudent to check actual operating temperatures in the application. Thermographic imaging is preferable; if this capability is not available, then thermocouples may be used. The use of AWG #40 gauge thermocouple is recommended to ensure measurement accuracy. Careful routing of the thermocouple leads will further minimize measurement error. Refer to Fig. G for the optimum measuring thermocouple location. (i) The output current at which any MOSFET temperature does not exceed a maximum specified temperature (110C) as indicated by the thermographic image, or (ii) The maximum current rating of the converter (10 A). During normal operation, derating curves with maximum FET temperature less than or equal to 110 C should not be exceeded. Temperature on the PCB at the thermocouple location shown in Fig. G should not exceed 110 C in order to operate inside the derating curves.
