Overview
The ISL97692IRTZ-T is a regulated PWM LED driver IC manufactured by Renesas Electronics Corporation. It features an integrated boost DC-DC converter topology with four independent output channels, each capable of delivering up to 40mA. The device operates on a supply voltage range of 2.4V to 5.5V and supports a switching frequency between 400kHz and 1.5MHz. It provides a maximum output voltage of 26V and includes internal switches for compact design. The component is housed in a 16-TQFN (3x3) package with exposed pad and functions within an ambient temperature range of -40°C to 85°C.
Feature Summary
- Integrates a boost DC-DC converter with four regulated current channels for uniform LED brightness control
- Supports high-resolution PWM dimming for precise light intensity adjustment without color shift
- Includes open LED protection circuitry to prevent damage during fault conditions
Applications
- LED backlighting systems for portable electronic devices
- General LED lighting applications requiring regulated current sources
- Battery-powered consumer electronics utilizing Li-Ion power supplies
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status as per latest manufacturer documentation. Check for End-of-Life notices or alternative part recommendations due to potential discontinuation. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity level classification.
Selection Notes
Select this component for designs requiring four independently regulated LED channels from a single boost converter. Suitable for low-voltage battery operation where space constraints favor a small QFN footprint. Consider thermal management requirements given the power dissipation characteristics of the TQFN package. Verify input voltage compatibility with the system's power source before integration.
Part Context
This part belongs to the ISL97692 series of LED drivers from Renesas. It is functionally related to other variants such as ISL97692IRTZ and ISL97692IIZ-T, differing primarily in packaging and shipping format. The series targets efficient LED illumination solutions with integrated regulation and dimming capabilities.
Replacement Considerations
