Overview
The HV9910CNG-G is a universal high-brightness LED driver IC manufactured by Microchip Technology, designed for buck topology applications. It operates with an input voltage range of 15 V to 450 V and features a fixed switching frequency of 100 kHz. The device provides adjustable output voltage and supports constant current regulation for single-channel outputs. Packaged in an SOIC-8 format, it functions within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum power dissipation of 650 mW and a maximum supply current of 1.5 mA.
Feature Summary
- Provides constant current regulation for high brightness LEDs without requiring external loop compensation
- Supports both linear dimming and PWM dimming capabilities for precise light control
- Integrates an internal linear regulator to simplify biasing requirements
Applications
- High brightness LED lighting systems
- General LED illumination drivers
- Buck converter based LED power supplies
Procurement Notes
Verify the end-of-life status before procurement, as this component is scheduled for obsolescence. Confirm that the SOIC-8 package aligns with your PCB footprint requirements. Ensure the 15 V to 450 V input range matches your system design. Check RoHS compliance documentation if required for your specific manufacturing standards. Validate that the 100 kHz switching frequency does not conflict with electromagnetic interference constraints in your application.
Selection Notes
Select this component when a buck topology is required for driving high brightness LEDs from a wide voltage input range. It is suitable for designs needing constant current regulation without complex compensation networks. Consider the SOIC-8 package size and thermal dissipation limits of 650 mW during layout. Verify compatibility with your desired dimming method, whether linear or PWM. Ensure the operating temperature range meets your environmental specifications.
Part Context
The HV9910 series was originally developed by Supertex before being acquired by Microchip Technology. This family includes variants such as the HV9910B and HV9910CLG-G, which share similar functional characteristics but may differ in packaging or minor electrical specifications. The HV9910CNG-G specifically utilizes the SOIC-8 package and is part of the broader universal high brightness LED driver lineup.
Replacement Considerations
The HV9910B is documented as an enhanced direct replacement for earlier HV9910 models. However, verify pinout and parameter compatibility with the HV9910CNG-G specifically. Other members of the HV9910 family, such as HV9910CLG-G, may serve as alternatives if package differences are acceptable.
