HV9961NG-G-M901

Overview

The HV9961NG-G-M901 is a DC-DC controller IC designed for LED driver applications, manufactured by Microchip Technology. It utilizes average-mode constant-current control and supports buck topology. The device accepts analog and PWM dimming inputs. It operates within a supply voltage range of 8V to 450V and functions across a temperature range of -40°C to 125°C. The component is housed in a 16-SOIC package with a width of 3.90mm.

Feature Summary

• Implements average-mode constant-current control for precise LED regulation
• Supports both analog and PWM dimming methods
• Designed for high-voltage buck converter topologies

Applications

• LED backlighting systems
• General LED lighting fixtures
• Commercial signage displays

Procurement Notes

Verify the specific suffix M901 to confirm tape-and-reel packaging requirements. Ensure compatibility with the 16-SOIC footprint during PCB layout. Confirm that the design accommodates the maximum 450V supply voltage rating. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when average-current mode accuracy is required for buck-based LED drivers. It is suitable for designs needing high input voltage support up to 450V. Consider the 16-SOIC package constraints and thermal management capabilities. Verify that the application requires both analog and PWM dimming interfaces.

Part Context

This part belongs to the HV9961 family of LED drivers from Microchip Technology (formerly Supertex). The family focuses on average-current mode control for high-performance lighting applications. Other variants include HV9961NG-G and HV9961LG-G, differing primarily in packaging or reel specifications.

Replacement Considerations

HV9910BNG-G is listed as a parameter-equivalent alternative.
