HV9967BK7-G

Overview

The HV9967BK7-G is an integrated LED driver IC from Microchip Technology, featuring average-mode current control and a buck topology. It operates within an input voltage range of 8 V to 60 V and delivers a regulated output current of 750 mA per channel. The device supports PWM dimming and includes built-in short circuit and thermal protection mechanisms. Designed for surface-mount assembly, it is housed in an 8-DFN package with dimensions of 3x3 mm. The component functions reliably across an ambient temperature range of -40°C to 125°C.

Feature Summary

• Integrates average-mode current control for precise regulation without external microcontrollers
• Includes internal high-side switch and protection against short circuits and thermal overload
• Supports digital PWM dimming for brightness adjustment

Applications

• LED backlighting systems
• General solid-state lighting fixtures
• Commercial signage displays

Procurement Notes

Verify the specific suffix 'BK7' confirms the 8-DFN (3x3 mm) package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure design compatibility with the specified 8 V to 60 V input range and 750 mA output capability. Validate that the application environment remains within the -40°C to 125°C operating temperature limits.

Selection Notes

Select this component for designs requiring a single-channel buck converter with integrated switching capabilities. It is suitable for applications needing constant current regulation up to 750 mA. Consider the 8-DFN footprint for space-constrained PCB layouts. Verify that the required input voltage does not exceed the 60 V maximum rating.

Part Context

This part belongs to the HV9967 series of LED drivers manufactured by Microchip Technology. The series focuses on providing efficient, compact solutions for LED illumination. The BK7 suffix specifically denotes the WDFN package configuration, distinguishing it from other pinout or housing variants within the same functional family.
