Overview
The HV9961NG-G-M934 is a Microchip Technology LED driver IC featuring average-current mode constant-current control. It operates in a buck topology with one output, supporting both analog and PWM dimming methods. The device functions within a supply voltage range of 8V to 450V and includes an internal switch. It is housed in a 16-SOIC package (0.154" width) and supports surface mount installation. Operating temperatures span from -40°C to 125°C.
Feature Summary
- Average current mode control eliminates peak-to-average error for improved accuracy without loop compensation or high-side sensing.
- Supports both analog and PWM dimming for flexible brightness control applications.
- Integrated buck DC-DC controller simplifies design by removing the need for external high-side current sensing components.
Applications
- LED backlighting systems
- General LED lighting fixtures
- Signage displays
Procurement Notes
Verify the specific suffix M934 indicates reel packaging when ordering. Confirm the 16-SOIC package dimensions match your PCB footprint requirements. Ensure input voltage does not exceed the 450V maximum rating. Check RoHS compliance status if required by your manufacturing standards. Validate thermal management capabilities for the 125°C operating limit.
Selection Notes
Choose this component for designs requiring precise LED current regulation without complex compensation networks. It is suitable for buck converter topologies where high efficiency is needed. Consider the 16-SOIC package size for space-constrained layouts. Verify compatibility with your chosen dimming signal type, as it supports both analog and PWM inputs.
Part Context
This part belongs to the HV9961 family of LED drivers from Microchip Technology. It shares core control features with variants like HV9961NG-G but differs in packaging configuration. The M934 suffix specifically denotes tape and reel packaging for automated assembly processes.
Replacement Considerations
HV9961NG-G is a parameter-equivalent alternative available in tube packaging. HV9910BNG-G is another equivalent option within the manufacturer's portfolio.
