XRP6670EVB: 2.5V @ 3A, 2.6 ~ 5.5V in

Summary

The Exar XRP6670 Evaluation board (EVB) is a fully assembled and tested surface-mount PCB that demonstrates the XRP6670 buck regulator. The XRP6670 is a synchronous current mode PWM step-down converter with integrated FET capable of delivering up to 3 Amps and optimized for portable battery operated applications. A 2.6V to 5.5V input voltage range allows for single supply operation from industry standard 3.3V and 5V power rails. Operating frequency is programmable between 300kHz and 2.5MHz via external resistor ROSC. The integrated P-channel control FET allows 100% duty cycle.

Built-in over-temperature, overcurrent, short circuit and under-voltage lock-out protection insure safe operation under abnormal operating conditions.

Connect a power supply to the VIN and GND pins of the PCB. Upon powering up the XRP6670 will regulate the VOUT at 2.5V nominal. XRP6670 is guaranteed to supply output current of up to 3A and provide nominal efficiency equal to figure 6 of the datasheet.
