• AEC-Q100 qualified buck regulator power module with integrated shielded inductor • 36VDC input voltage, 1.5A output current • SCP, OCP, OTP, and UVLO protection • 3.0 x 5.0mm low profile QFN package • Wettable flanks for optical inspection on request • Enable, power good, soft start, and sync functions • -40 to 125°C operating temperature Features Power Module Description The RPX-1.5Q is an automotive-grade buck converter with an integrated inductor in a compact 3mm x 5mm x 1.6mm thermally-enhanced QFN package (wettable flank version available on request). The input range is from 4 to 36VDC, allowing 5V, 12V, or 24V supply voltages to be used. The output voltage can be set with two resistors in the range from 0.8 up to 30VDC. The output current is up to 1.5A and is fully protected against continuous short-circuits, output overcurrent, or over-temperature faults.
