White LEDs Driver for up to 2LEDs in series, 5 strings
BD6079GWL
General Description
BD6079GWL is a boost-up DC/DC type white LED driver IC with synchronous rectification that can drive up to 10 LEDs, arranged in 1-5 strings of 2LEDs in Series, with string LED Cathodes connected to GND. With synchronous rectification (no external schottky diode required) and small package, it is possible to save mount space. The brightness of LED can be adjusted by using PWM pulse on EN pin. (PWM Frequency :100Hz~1600Hz) LED current is set by resistance at ISET terminal.
