ISL97672BIRZ

Overview

The ISL97672BIRZ is a six-channel LED driver IC manufactured by Renesas Electronics Corporation. It features an integrated boost DC-DC converter topology with internal switches, designed for backlight applications. The device supports PWM dimming and operates within a supply voltage range of 4.5V to 26.5V, delivering up to 50mA per channel with a maximum output voltage of 45V. Operating frequencies are adjustable between 200kHz and 1.5MHz. It is housed in a 20-QFN (3x4) package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost DC-DC converter with internal switches for efficient power management
• Provides independent current regulation across six output channels
• Supports high-resolution PWM dimming control for brightness adjustment

Applications

• LCD backlight systems
• Monitor displays
• Television sets

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IRZ' indicates lead-free RoHS compliance and tube packaging. Check for End-of-Life notices as availability may be restricted. Ensure ESD handling protocols are followed during installation due to the QFN package type.

Selection Notes

Select this component when designing circuits requiring six independently regulated LED channels from a single boost regulator. It is suitable for applications needing adjustable switching frequencies to optimize external component size. Consider thermal performance requirements given the compact QFN package and internal switch integration.
