The RPY-1.5Q is an automotive grade constant current source buck regulator designed for driving high power LEDs. The integrated inductor means that a complete LED driver can be realized in a compact 3mm x 5mm x 1.6mm thermally-enhanced QFN package with a maximum current output of up to 1500mA set with an external sense resistor. The input voltage range is from 4 to 36VDC, allowing 5V, 12V, or 24V supply voltages to be used. The output is fully protected against continuous short-circuits, input undervoltage, output overcurrent, or over-temperature conditions. A fault indicator flags thermal shutdown or LED open/short circuit conditions. Applications include dimmable LED lighting, visible or IR LED illumination for drones and robotic camera systems, or precision high current CC sources for test and measurement use.
