Description
This reference design contains two duplicate LED drivers. Each circuit drives a 10V to 50V series connected string of LEDs at 350mA. The input range is 55VDC to 75VDC. The TPS40210 boost controller is used in an "upside-down" buck topology for a simple, low-cost solution. This circuit includes an enable, PWM dimming, current trimming, and a current sense functions for interfacing with an external microprocessor.
