HV9986K6-G

Overview

The HV9986K6-G is a three-channel closed-loop LED driver IC manufactured by Microchip Technology. It integrates SEPIC, buck, and boost DC-DC controller topologies to support diverse LED lighting architectures. The device features analog and PWM dimming capabilities for precise light control. It is housed in a 40-pin VQFN (6x6 mm) package. The component operates with an external reset function and is designed for high-efficiency power conversion in solid-state lighting applications.

Feature Summary

• Supports multiple DC-DC converter topologies including SEPIC, buck, and boost configurations.
• Provides three independent output channels with closed-loop current regulation.
• Enables flexible illumination control through combined analog and pulse-width modulation dimming interfaces.

Applications

• General solid-state LED lighting systems
• Architectural accent lighting fixtures
• Commercial downlight and track lighting modules

Procurement Notes

Verify the active status of this component as distribution sources indicate end-of-life or discontinuation status. Confirm availability through authorized Microchip Technology representatives or verified distributors. Ensure that any substitute components maintain compatibility with the required three-channel topology and package dimensions for your specific design implementation.

Selection Notes

Select this driver for designs requiring multi-zone LED control within a single integrated circuit. The inclusion of SEPIC capability allows operation from input voltages both above and below the LED string voltage. Evaluate thermal performance requirements for the 40-QFN package when designing for high-power density applications.

Part Context

This part belongs to the HV9986 family of LED drivers from Microchip Technology. It is distinct from the HV9985 series which may lack specific integration features. The K6 suffix typically denotes the specific package variant and temperature grade. This component serves as a specialized solution for complex LED arrays requiring synchronized multi-channel management.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Due to the discontinued status indicated by some suppliers, engineers must identify equivalent devices based on pinout compatibility and electrical specifications rather than direct cross-reference lists.
