Overview
The HV9910CNG-G-M934 is a high-brightness LED driver IC from Microchip Technology, designed for constant-current control in lighting applications. It operates as a buck converter with an input voltage range of 15 V to 450 V and supports PWM dimming. The device features a 16-SOIC package and functions within a temperature range of -40°C to +125°C. It eliminates the need for external loop compensation, simplifying design implementation for single-output LED systems.
Feature Summary
- Provides precise constant-current regulation for high-brightness LEDs without requiring external loop compensation components.
- Supports digital PWM dimming for efficient brightness control across a wide operating range.
- Integrates a buck topology suitable for high-voltage input sources up to 450 V.
Applications
- General solid-state lighting fixtures
- High-brightness LED illumination systems
- Commercial and industrial LED drivers
Procurement Notes
Verify the specific suffix M934 against the official Microchip datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Cross-reference thermal requirements with system constraints given the extended operating temperature range. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement.
Selection Notes
Select this component when designing buck-converter-based LED drivers requiring high input voltage tolerance and simplified compensation networks. It is suitable for applications needing reliable constant-current performance with integrated PWM dimming capabilities. Consider the 16-SOIC package size for space-constrained designs requiring robust thermal management within the specified operating temperature limits.
Part Context
This part belongs to the HV9910 series of universal high-brightness LED drivers. The series is characterized by its ability to drive LEDs directly from high-voltage DC sources without complex feedback loops. The HV9910C variant specifically denotes the commercial temperature grade and SOIC packaging configuration within the broader product family.
Replacement Considerations
HV9910CNG-G is a verified equivalent part number offering identical electrical characteristics and functionality. Verify that any substitute maintains the same 16-SOIC footprint and thermal performance metrics to ensure seamless integration into existing hardware designs.
