1A WHITE LED DRIVER WITH PWM DIMMING CONTROLLER

The SD42511 is a Step-down PWM control LED Driver with a built-in internal Power MOSFET It achieves 1A continuous output current over a wide input supply range. It provides thermal shutdown circuit, current limiting circuit and PWM dimming circuit. SD42511 adopts current mode control. Current mode operation provides fast transient response and simple loop stabilization design. SD42511 has high efficiency up to more than 90%, and has excellent constant current characteristic when the input/output voltage changed, with the excellent current accuracy within 1%. With the high input voltage of up to 25V and built-in slope compensation, it CAN drive 6 LEDs By Silan
