The input range is from 2.5 to 6.0VDC for use in low power/low voltage systems. The tightly regulated output voltage can be set with two resistors in the range from 0.6V up to 5.25V. The output current is up to 3A and is fully protected against continuous short-circuits, output overcurrent or over-temperature faults. Its high current and small size make the RPZ-3.0 ideal for optical modules, industrial PCs, machine imaging systems, distributed power architectures, portable equipment in telecom as well as industrial applications. |Selection Guide

Notes:
Note6: The RPZ-3.0 requires 2x 10µF MLCC input capacitors as close as possible to VIN and GND pin and 3x 10µF output capacitors to reduce noise.
Note7: Transient load reaction time can be improved by adding a feed-forward capacitor, CFF across VOUT and FB pin, but it is not required for normal operation.

REV.: 0/2022 I-2 **www.recom-power.com** ## **RPZ-3.0** ## **DC/DC Converter** ## **Series** ## Specifications ## OUTPUT VOLTAGE SETTING A resistor divider connected to the FB pin (pin 8) sets the output voltage of the RPZ-3.0. The output voltage adjustment range is from 0.6VDC to 5.25VDC. The schematic below shows the feedback resistor connections for setting the output voltage. The recommended value of R1 is 100k Ω . Use the equation to calculate the value for R2. The table below lists the R2 resistor values according to standard E96 values; therefore, the specified voltage may slightly vary. ## Feedback Network |FB
