Product Description

The TPS92511DDA is a 30W Anode Capable Constant Current Buck LED Driver for driving a single LED string with current up to 0.5A and efficiency up to 95%. Only 5 external components are required for basic operation and single layer PCB layout is feasible because of the integration of an N-MOSFET, no external current sensing resistor, no external compensation and the proper terminal assignment. A high-value external resistor programs the LED current so that fine tuning of the LED current can be achieved. Another high-value external resistor programs a constant switching frequency from 50 to 500kHz. EMI design becomes easier as a result of constant switching frequency. By adding simple external circuits, the device can handle applications with even higher input voltages. It applies a floating buck topology with a low-side N-channel power MOSFET, which does not need boot-strapping capacitor.
