GM9910B Datasheet | Gamma

UNIVERAL HIGH BRIGHTNESS LED DRIVER Description The GM9910B is a PWM high efficiency control LED driver IC. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 10VDC up to 500VDC, this feature allows GM9910B can work from a wide range of input voltages without the need for an external low voltage supply. By using a single resistor, the switching frequency to control the external MOSFET can be fixed up to 300KHz. GM9910B is constant current LED driver, which enhance the reliability. The output current can be programmed between a few milliamps and up to more than 1.0A. GM9910B uses a rugged high voltage junction isolated process that can...
