HV9910BNG-G-M934

Overview

The HV9910BNG-G-M934 is a single-output DC-DC controller IC designed for LED lighting applications, manufactured by Microchip Technology. It operates in a buck topology with an input voltage range of 8V to 450V and supports switching frequencies of 25kHz and 100kHz. The device features PWM and analog dimming capabilities and is housed in a 16-SOIC package. It functions as a constant current driver without internal switches.

Feature Summary

• Supports both PWM and analog dimming methods for precise light control
• Operates as a buck converter topology for step-down voltage regulation
• Provides constant current output suitable for high-brightness LEDs

Applications

• Backlighting systems
• General illumination
• Signage

Procurement Notes

Verify the specific suffix M934 against official datasheets to confirm packaging details such as reel size or tape specifications. Ensure compatibility with the required operating temperature range of -40°C to 125°C. Cross-reference the part number with Microchip's latest documentation to confirm RoHS compliance status and any recent design changes or PCNs affecting this specific variant.

Selection Notes

Select this component when a buck topology is required for LED drivers with wide input voltage ranges up to 450V. It is suitable for designs needing integrated PWM and analog dimming control within a 16-SOIC footprint. Consider thermal management requirements given the 125°C maximum junction temperature rating and surface mount installation type.

Part Context

This part belongs to the HV9910 series of universal high-brightness LED drivers from Microchip Technology. The series includes variants like HV9910CLG-G and HV9910BDB3, differing primarily in package types and specific feature sets. The HV9910BNG-G-M934 specifically denotes the buck topology version in a 16-pin SOIC package.

Replacement Considerations

HV9910NG-G is listed as a parameter-equivalent substitute.
