Overview
The HV9982K6-G is a three-channel closed-loop Switch Mode LED driver IC from Microchip Technology. It operates within an input voltage range of 10 V to 40 V and supports Boost, Buck, and SEPIC topologies. The device features adjustable output voltage and delivers up to 400 mA per channel at a switching frequency of 500 kHz. Packaged in a QFN-40 format, it functions between 0°C and +85°C with a maximum power dissipation of 5 W.
Feature Summary
- Integrates three independent channels for closed-loop LED regulation
- Supports multiple converter topologies including Boost, Buck, and SEPIC
- Includes PWM dimming capability for brightness control
- Provides short circuit and thermal protection mechanisms
Applications
- LED lighting systems requiring multi-channel regulation
- General illumination applications using Switch Mode drivers
- Industrial or commercial LED fixtures with specific topology needs
Procurement Notes
Verify the exact ordering suffix and package variant against the official Microchip datasheet before procurement. Confirm that the QFN-40 package matches your PCB footprint requirements. Ensure the supply chain source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number to avoid counterfeit components. Check for any specific handling instructions regarding humidity sensitivity during storage.
Selection Notes
Select this component when a single IC must manage three separate LED channels with closed-loop accuracy. It is suitable for designs utilizing Boost, Buck, or SEPIC architectures. The 400 mA output current per channel fits moderate-power LED strings. Consider the 500 kHz switching frequency for passive component sizing. Verify that the 10 V to 40 V input range aligns with the system power supply.
Part Context
This part belongs to the HV9982 family of Switch Mode LED drivers. It is designed by Microchip Technology for efficient LED control. The K6-G suffix typically denotes the specific package and environmental compliance version. It serves as a solution for integrating multiple drive channels into a compact form factor.
Replacement Considerations
Consult the official Microchip datasheet for confirmed substitute part numbers. Do not assume functional equivalence with other HV series parts without verifying pinouts and electrical specifications. Check for updated revisions that may alter performance characteristics.
