XRP7613EVB: 1.2A @ 15V Max, 7 ~ 36Vin

The Exar XRP7613 Evaluation board (EVB) is a fully assembled and tested surface-mount PCB that demonstrates the XRP7613 LED driver. The XRP7613 is a non-synchronous step-down converter with integrated FET optimized to drive high-power LEDs at up to 1.2 A of continuous current. A wide 7.0 V to 36 V input range allows for single supply operation from industry standard 12 V, 18 V, or 24 V power rails.

Based on a hysteretic PFM control scheme, the XRP7613 can operate at switching frequency of up to 1 MHz and allows for small external components selection while providing very fast transient response and achieving excellent efficiency. The output current is programmable from 150 mA to 1.2 A through an external sense resistor.
