ISL97692IIZ-T

Overview

The ISL97692IIZ-T is a four-channel LED lighting driver IC designed for single-cell lithium-ion battery-powered applications. It integrates a boost DC-DC converter with an internal switch, supporting output voltages up to 26V and channel currents of 40mA. The device operates on a supply voltage range of 2.4V to 5.5V and features a switching frequency between 400kHz and 1.5MHz. It provides 12-bit PWM dimming control for brightness adjustment. The component is housed in a 16-WFQFN exposed pad package (16-TQFN 3x3) and supports surface-mount installation.

Feature Summary

• Integrates a four-channel LED driver with a built-in boost DC-DC converter topology
• Supports 12-bit pulse-width modulation (PWM) dimming for precise brightness control
• Designed for operation from a single-cell lithium-ion battery power source

Applications

• LED backlighting systems
• Portable electronic devices powered by single-cell Li-Ion batteries

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics Corporation. Distribution channels indicate restricted availability or discontinuation. Verify current stock status and obsolescence notifications through authorized distributors before design implementation. Sourcing may require checking secondary market suppliers or alternative lifecycle management options.

Selection Notes

Select this part for designs requiring four independent LED channels driven by a single-cell lithium-ion battery. Ensure the application demands a boost topology with output voltages up to 26V. The 12-bit PWM resolution suits applications requiring fine-grained brightness control. Verify thermal requirements for the 16-TQFN package and confirm compatibility with the specified operating temperature range of -40°C to 85°C.

Part Context

The ISL97692 series belongs to Renesas' portfolio of dedicated LED lighting drivers. This specific model targets portable consumer electronics where space efficiency and single-cell battery operation are critical. It combines power conversion and LED driving functions into a compact integrated circuit, reducing external component count compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the EOL status. Designers should consult Renesas technical support for cross-reference recommendations or evaluate newer generations within the LED driver family.
