Conception de référence par: Texas Instruments
PMP4936, 50Vdc-60Vdc Input,2-Channel,350mA LED Driver (10V to 40V String). Reference design contains two duplicate LED drivers. Each circuit drives a 10V to 40V series connected string of LEDs at 350mA. The input range is 50VDC to 60VDC. The TPS40210 boost controller is used in an "upside-down" buck topology for a simple, low-cost solution. This circuit includes synchronization, enable, PWM dimming, current trimming, and a current sense functions for interfacing with an external Microprocessor
