www.DataSheet4U.com HV9910 Universal High Brightness LED Driver Features >90% Efficiency 8V to 450V input range Constant-current LED driver Applications from a few mA to more than 1A Output LED string from one to hundreds of diodes PWM Low-Frequency Dimming via Enable pin Input Voltage Surge ratings up to 450V Description The HV9910 is a PWM high-efficiency LED driver control IC. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC. The HV9910 controls an external MOSFET at fixed switching frequency up to 300kHz. The frequency can be programmed using a single resistor. The LED string is driven at constant current rather than constant voltage, thus providing constant light output and enhanced reliability.
