ISL97683IRTZ-TK

Overview

The ISL97683IRTZ-TK is a highly integrated LED driver from the ISL97682/3/4 series, designed for medium-size TFT-LCD backlights. It features selectable switching frequencies of 600kHz or 1MHz in PWM/PFM modes and incorporates dynamic headroom control to minimize output ripple. The device supports up to 45V output voltage and includes fault protections such as string open/short circuit detection, overvoltage protection (OVP), and overtemperature protection (OTP). It operates within an ambient temperature range of -40°C to +85°C.

Feature Summary

Adaptive boost switching architecture with direct PWM dimming capability
Dynamic headroom control for optimized regulation and ripple reduction
Comprehensive fault protection including OVP, OTP, and string diagnostics

Applications

Medium-size TFT-LCD backlighting systems
Video and audio equipment requiring low noise interference
Portable electronic devices with AC input requirements

Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape and reel packaging specifications. Ensure compatibility with system voltage ranges and thermal management requirements before integration. Cross-reference part numbers with current manufacturer availability lists as distribution status may vary.

Selection Notes

Select this component for applications requiring flexible frequency tuning between 600kHz and 1MHz. The integrated phase shift control helps eliminate video and audio noise interference. Consider the compact TQFN-16 package for space-constrained designs requiring high integration levels.

Part Context

This part belongs to the ISL97682/3/4 family of LED drivers. These components are engineered for high efficiency and minimal external component count. They support bootstrap configurations for lower input voltages and offer 8-bit PWM dimming for precise brightness control in display applications.

Replacement Considerations

ISL97682IRTZ-TK and ISL97684IRTZ-TK are pin-compatible members of the same series. Verify channel count requirements as these variants differ in the number of supported LED channels while maintaining identical electrical characteristics and package dimensions.
