ISL97632IRT14Z-TK

Overview

The ISL97632IRT14Z-TK is a white LED driver IC designed for backlighting applications. It features an integrated step-up DC-DC regulator capable of driving up to seven white LEDs with a regulated output current of 70mA. The device supports digital dimming via a single-wire interface and operates within an input voltage range of 2.4V to 5.5V. Packaged in an 8-TDFN (2x3) footprint, it includes an internal Schottky diode and overvoltage protection.

Feature Summary

• Integrates a boost converter for efficient white LED backlighting
• Supports dynamic digital dimming through a single-wire interface
• Includes an integrated Schottky diode to reduce external component count

Applications

• Backlighting for LCD displays using 2 to 7 white LEDs
• Portable electronic devices requiring regulated LED illumination
• Systems utilizing single-wire control interfaces for brightness adjustment
