TPS92511DDAR Description

The TPS92511DDAR 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%. The TPS92511DDAR 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. The TPS92511DDAR employs a proprietary control scheme to regulate the LED current without the need of sensing the LED current directly.
