The XRP7613 is a non-synchronous step down converter with integrated FET optimized to drive high power LEDs at up to 1.2A of continuous current. A wide 7.0V to 36V input voltage range allows for single supply operations from industry standard 12V, 18V or 24V power rails.
Based on a hysteretic PFM control scheme, the XRP7613 can operate at switching frequency of up to 1MHz and allows for small external components selection while providing very fast transient response and achieving excellent efficiency. The output current is programmable from 150mA to 1.2A through an external sense resistor.
Output current dimming is supported through an analog signal or PWM logic signal at up to 40kHz. A dynamic LED current thermal control further enhances the reliability of the end application by linearly reducing the LED current as temperature raises.
An open LED, LED short circuit, over temperature and under voltage lock out protection insures safe operations under abnormal operating conditions.
The XRP7613 is offered in RoHS compliant, "green"/halogen free 8-pin Exposed Pad SOIC package.
