HV9912NG-G-M934

Overview

The HV9912NG-G-M934 is a switch-mode LED driver IC manufactured by Microchip Technology, designed for high-current accuracy applications. It functions as a DC-DC controller supporting SEPIC, buck, and boost topologies with integrated hiccup mode protection. The device operates within a supply voltage range of 9V to 250V and supports switching frequencies of 100kHz and 350kHz. It features PWM dimming capabilities and is housed in a 16-SOIC package. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrated hiccup mode protection for enhanced system reliability under fault conditions
• Supports multiple converter topologies including SEPIC, step-down (buck), and step-up (boost)
• Enables precise current regulation suitable for high-performance LED lighting applications

Applications

• LED backlighting systems
• General LED lighting drivers
• Industrial power management circuits requiring isolated or non-isolated DC-DC conversion

Procurement Notes

Verify the specific suffix M934 against your Bill of Materials to ensure correct packaging configuration. Confirm that the 16-SOIC package dimensions match your PCB footprint requirements. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process. Ensure input voltage specifications align with your system's power supply rails before integration.

Selection Notes

Select this component when designing LED drivers that require flexibility in topology choice, such as transitioning between buck and boost modes. It is suitable for applications demanding high current accuracy without external sensing complexity. Consider the 16-SOIC package size for space-constrained designs. Evaluate thermal performance requirements given the operating temperature range and power dissipation characteristics inherent to switch-mode operation.
