HV9921N3-G Description

Short technical summary and product information.

The HV9921N3-G from Microchip Technology is a pulse-width modulated (PWM), high-efficiency LED driver control IC designed for decorative lighting and low power lighting fixtures. It allows for efficient operation of LED strings from voltage sources up to 400VDC.

 

This IC features a constant output current of 20mA and operates across a universal AC line voltage range of 85 to 264VAC, or a DC input voltage of 20 to 400V. It incorporates an internal 475V power MOSFET and utilizes a fixed off-time buck converter topology. The peak current control scheme ensures good regulation of the output current.

 

The HV9921N3-G supports Triac dimming, providing constant light output and enhanced reliability for LED strings. It is housed in a TO-92-3 package and is designed for through-hole mounting.

 

Key specifications include an operating temperature range of -40°C to 85°C (TA) and a fixed off-time of approximately 10 μs. The device is RoHS3 compliant.
