Overview
The ISL97632IRT14Z-T is a highly integrated PWM boost LED driver IC manufactured by Renesas Electronics Corporation. Designed for portable applications, it drives white LEDs with an output current of 70mA. The device operates within a supply voltage range and supports digital dimming control. It is housed in an 8-TDFN (2x3) package with an exposed pad, suitable for surface mount assembly. This component serves as a DC-DC regulator step-up converter optimized for backlighting small LCD panels.
Feature Summary
- Integrates a PWM boost converter for efficient LED driving
- Supports digital dimming control for brightness adjustment
- Compact 8-TDFN package design minimizes board space
Applications
- Backlighting for 1.8-inch to 3.5-inch LCD displays
- Portable electronic devices requiring compact LED drivers
- White LED illumination systems in handheld instruments
Procurement Notes
Verify the exact suffix 'T' indicates tape and reel packaging when ordering. Confirm the manufacturer is Renesas Electronics Corporation, formerly Intersil. Check for RoHS compliance status on the specific lot. Ensure the 8-TDFN footprint matches your PCB layout requirements before procurement.
Selection Notes
Select this part for designs requiring a single-channel boost driver for small LCD backlights. It is suitable where board space is limited due to its small TDFN package. Consider the 70mA output current limit when sizing the LED string. Verify input voltage compatibility with the system power rail.
Part Context
This component belongs to the ISL97632 series of LED drivers from Renesas. It is functionally similar to other models in the family but may differ in pinout or specific electrical characteristics. The 'IRT14Z-T' suffix denotes the specific package type and shipping configuration. It replaces older discrete LED driver solutions in portable display applications.
Replacement Considerations
Check datasheets for direct pin-to-pin replacements within the ISL9763x family. Verify that alternative parts support the same 70mA output current and digital dimming interface. Ensure the replacement package matches the 8-TDFN form factor for mechanical compatibility.
