Overview
The HV9912NG-G-M901 is a switch-mode LED driver IC manufactured by Microchip Technology, designed for high-accuracy current regulation in lighting applications. It operates as a DC-DC controller supporting SEPIC, buck, and boost topologies within a 16-pin SOIC package. The device features an operating supply voltage range of 9V to 100V and supports switching frequencies of 106kHz and 580kHz. It provides analog and PWM dimming capabilities with a junction temperature range of -40°C to 125°C.
Feature Summary
- Supports multiple converter topologies including SEPIC, buck, and boost configurations for flexible LED drive designs.
- Enables precise light control through integrated analog and pulse-width modulation (PWM) dimming interfaces.
- Incorporates hiccup mode protection to manage fault conditions and enhance system reliability during operation.
Applications
- General LED illumination systems
- Backlighting drivers for displays
Procurement Notes
Verify the specific suffix M901 corresponds to tape-and-reel packaging containing 2600 units per reel. Confirm RoHS3 compliance status and ensure the 16-SOIC footprint matches the target PCB layout. Cross-reference the datasheet revision date to validate technical specifications against current manufacturing standards.
Selection Notes
Select this component when designing flyback or isolated LED drivers requiring high current accuracy. It is suitable for applications needing both analog and digital dimming control. Ensure the input voltage stays within the 9V to 100V range and verify thermal management for the SOIC package under maximum load conditions.
Part Context
This part belongs to the HV9912 family of switch-mode LED drivers from Microchip Technology. It shares functional similarities with other members like the HV9911 but offers specific frequency options and voltage ranges tailored for general lighting and backlighting needs. The M901 suffix indicates the specific packaging configuration used for automated assembly.
Replacement Considerations
Direct substitutes include the HV9911NG-G-M901, which offers similar functionality with different frequency characteristics. Verify pin compatibility and electrical parameters before swapping components in existing designs.
