3-PIN Switch Mode LED Lamp Driver IC
Description
HV9921/HV9922/HV9923 are pulse-width modulated (PWM), high-efficiency, LED driver control ICs. They allow efficient operation of LED strings from voltage sources ranging up to 400VDC. HV9921/22/23 include an internal high voltage switching MOSFET controlled with fixed off-time (TOFF) of approximately 10µs. The LED string is driven at constant current, thus providing constant light output and enhanced reliability. The output current is internally fixed at 20mA for HV9921, 50mA for HV992, and 30mA for HV9923. The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range of 85 to 264VAC or DC input voltage of 20 to 400V.
