Overview
The HV9963NG-G-M934 is a closed-loop LED driver IC from Microchip Technology, designed for high-performance lighting applications. It supports Buck, Boost, and SEPIC topologies within an input voltage range of 8 V to 40 V. The device operates at a fixed switching frequency of 520 kHz and features enhanced PWM dimming capabilities. Packaged in a 16-SOIC format, it includes open LED protection and functions reliably across temperatures from -40°C to +125°C.
Feature Summary
- Supports Buck, Boost, and SEPIC converter topologies for flexible LED drive configurations
- Integrated enhanced PWM dimming control for precise brightness adjustment
- Built-in open LED protection circuitry to safeguard the load and driver
- Closed-loop regulation ensures stable LED current despite input or load variations
Applications
- General solid-state lighting fixtures
- Industrial LED illumination systems
- Automotive exterior lighting modules
Procurement Notes
Verify the specific suffix M934 corresponds to the tape and reel packaging configuration when ordering. Confirm that the 16-SOIC footprint matches your PCB design constraints. Ensure the input voltage supply remains within the 8 V to 40 V operational window to maintain proper controller functionality and thermal performance.
Selection Notes
Select this component when a single-output driver supporting multiple topologies is required. It is suitable for designs needing wide input voltage ranges and robust protection features. Consider the 520 kHz frequency for balancing efficiency and component size. Verify compatibility with your microcontroller for PWM dimming signals if external control is utilized.
Part Context
This part belongs to the HV9963 family of closed-loop LED drivers. It shares core architecture with variants like HV9963NG-G but differs in packaging media. The M934 suffix specifically denotes the reel packing option, distinguishing it from tube-packed equivalents while maintaining identical electrical characteristics and pinout.
Replacement Considerations
HV9963NG-G is a functional equivalent with identical electrical specifications but utilizes tube packaging instead of tape and reel. Verify that the change in physical packaging does not impact automated assembly processes before substitution.
