ISL97672AIRZ

Overview

The ISL97672AIRZ is a six-channel LED driver IC featuring an integrated boost DC-DC converter and PWM dimming control. It 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. The device supports switching frequencies between 200kHz and 1.5MHz and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 20-QFN (3x4) format, it is designed for high-efficiency backlighting applications requiring precise current regulation.

Feature Summary

Integrates a boost topology DC-DC converter for efficient power management
Provides independent current regulation for six distinct LED channels
Supports high-resolution PWM dimming for brightness control

Applications

LCD monitor backlighting
Notebook display backlighting

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'AIRZ' matches design requirements, as packaging variations exist. Check official documentation for end-of-life status updates, as availability may be restricted. Ensure thermal and electrical parameters align with target system specifications before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring multi-channel LED regulation with integrated power conversion. Evaluate the 20-QFN package constraints against PCB layout limitations. Consider the 200kHz to 1.5MHz frequency range for inductor selection and EMI performance. Verify that the 45V output capability meets the series LED forward voltage requirements of the application.

Part Context

This part belongs to the ISL97672 family of LED drivers from Renesas Electronics. It shares functional similarities with variants like the ISL97672BIRZ but differs in specific operational characteristics and packaging options. The series targets portable electronics and display systems where space efficiency and multi-channel control are critical design factors.
