The HV9922N8-G from Microchip Technology is a high-efficiency, pulse-width modulated (PWM) LED driver control IC. It is designed to enable efficient operation of LED strings from universal AC line voltage sources ranging from 85 to 264VAC, or DC input voltages from 20 to 400V.
This device features an internal 475V power MOSFET and operates as a fixed off-time buck converter. The output current is internally fixed at 50mA, ensuring constant light output and enhanced reliability for the LED string. It also includes Triac dimming capability.
The HV9922N8-G is housed in a SOT-89-3 (TO-243AA) surface-mount package, making it suitable for various lighting applications. Its operating temperature range is -40°C to 85°C (TA).
Key features include a universal 85-264VAC operation, a fixed off-time of approximately 10 μs, and an internal high voltage switching MOSFET. The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range.
