TPS92511 Constant Current Buck LED DriverTexas Instruments TPS92511 Constant Current Buck LED Driver is an easy-to-use 65V constant current buck converter for driving a single LED string. This allows current up to 0.5A and with an efficiency of up to 95%. Only 5 external components are required for basic operation. A single-layer PCB layout is feasible because of the integration of an N-MOSFET. There is no external current sensing resistor, no external compensation and it includes 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 50kHz to 500kHz. EMI design becomes easier as a result of the constant switching frequency. The TPS92511 from Texas Instruments provides a wide input voltage range from 4.5V to 65V. By adding simple external circuits, the device can handle applications with even higher input voltages.
