More Information
The TPS92511 is an easy to use 65V constant current buck converter 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 a 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 50kHz to 500kHz. EMI design becomes easier as a result of constant switching frequency. The TPS92511 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.
