The XRP7613IDBTR-F is a non-synchronous Step-down Converter with integrated FET optimized to drive high power LEDs at up to 1.2A of continuous current. The high brightness LED driver has a wide current of 7 to 36V input voltage range allows for a single supply operations from industry standard 12, 18 or 24V power rails. Based on a hysteretic PFM control scheme, the XRP7613 can operate at switching frequency 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 sensor resistor. Output current dimming is supported through an analogue 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.

• LED current fold back thermal control
• Shutdown control
• Built-in soft-start
• PWM and analogue dimming capability
