Overview
The HV9910BNG-G is a universal high-brightness LED driver IC manufactured by Microchip Technology. It operates as a single-output DC-DC controller utilizing a step-down (buck) topology. The device supports an input voltage range from 8 V to 450 V and functions at a switching frequency of 100 kHz. It provides adjustable output voltage and delivers a constant current capability of up to 165 mA. The component is housed in a 16-SOIC package and is designed for operation within a temperature range of -40°C to +125°C.
Feature Summary
- Supports PWM dimming and analog dimming capabilities for precise light control
- Integrates constant current regulation architecture for stable LED performance
- Features internal linear regulator and soft-start functionality
Applications
- High brightness LED lighting systems
- Offline LED driver designs
- General illumination applications
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance status before procurement. Confirm the 16-SOIC package dimensions match the target PCB footprint. Ensure the design accommodates the specified 8 V to 450 V input range requirements. Check for any end-of-life notices or obsolescence warnings associated with this specific part number variant.
Selection Notes
Select this component when a buck topology is required for high-voltage LED strings. It is suitable for designs needing integrated PWM dimming without external controllers. Consider the 165 mA output limit when sizing the LED array. Verify that the 16-pin SOIC package fits the assembly constraints compared to the 8-pin alternative.
Part Context
This part belongs to the HV9910 series, which includes variants like the HV9910BLG-G in an 8-pin package. The HV9910B represents an improved version of the original HV9910, offering enhanced performance characteristics while maintaining compatibility with existing design architectures for high-brightness LED drivers.
Replacement Considerations
The HV9910B is the direct predecessor and functional equivalent. The HV9910BLG-G offers identical electrical specifications but utilizes an 8-pin SOIC package instead of the 16-pin configuration.
