Overview
The HV9910CSG-G is a universal high-brightness LED driver IC from Microchip Technology, designed for buck topology applications. It operates within a supply voltage range of 15 V to 450 V and supports an adjustable output voltage. The device functions at a fixed working frequency of 100 kHz and provides a single output channel. Packaged in an SOIC-8 format, it is rated for operation between -40°C and +125°C with a maximum power dissipation of 650 mW.
Feature Summary
- Supports PWM dimming for precise brightness control
- Maintains constant current regulation for LED stability
- Operates across a wide universal input voltage range
Applications
- High brightness LED lighting systems
- Universal AC/DC LED driver designs
- Industrial LED illumination fixtures
Procurement Notes
Verify the specific suffix 'CSG' to confirm the SOIC-8 reel packaging configuration. Confirm RoHS compliance status through official Microchip documentation prior to integration. Check for end-of-life notifications as availability may be restricted. Ensure thermal management aligns with the 650 mW power dissipation limit in the final assembly design.
Selection Notes
Select this component when a buck converter topology is required for high-voltage LED strings. The 100 kHz switching frequency offers a balance between efficiency and component size. Verify that the application requires a single-channel constant current source. Ensure the operating environment stays within the specified -40°C to +125°C temperature range for reliable performance.
Part Context
This part belongs to the HV9910 series of LED lighting drivers. The series includes variants such as the HV9910CLG-G and HV9910P-G, which share similar electrical characteristics but differ in package types like SOIC-8 or PDIP-8. The HV9910CSG-G specifically denotes the surface-mount variant optimized for automated assembly processes.
Replacement Considerations
The HV9910CLG-G is a documented alternative within the same family, offering identical electrical specifications in a compatible SOIC-8 package. Verify pinout compatibility and thermal requirements before substitution.
