IS31FL3726A-ZLS4-TR

Overview

The IS31FL3726A-ZLS4-TR is a linear LED driver IC featuring 16 output channels housed in a 24-pin eTSSOP package. It operates on a supply voltage range of 3V to 5.5V, delivering up to 25.2mA per channel. The device utilizes a shift register topology and supports PWM dimming at frequencies up to 30MHz via a serial interface. Designed for surface mount installation, it functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

Integrates 16 constant current channels with internal linear switching topology
Supports high-speed serial communication interfaces for data transmission
Enables precise brightness control through independent PWM dimming capabilities

Applications

Backlighting systems for displays
General LED lighting applications
Consumer electronics indicator circuits

Procurement Notes

Verify the specific suffix ZLS4 confirms the eTSSOP-24 package variant, as other suffixes like QFLS2 indicate different packages such as QFN. Confirm component status, as related variants may be discontinued or subject to product change notifications. Ensure compatibility with the required operating temperature range and verify RoHS compliance status for the specific manufacturing batch before integration into final designs.

Selection Notes

Select this component when a 16-channel solution with a 24-pin eTSSOP footprint is required. Compare against the IS31FL3726-QFLS2-TR if a smaller QFN package is preferred instead. Consider the IS31FL3726A-QFLS4-TR for potential availability improvements or updated revisions. Evaluate the 25.2mA output capability against load requirements to ensure sufficient drive strength without external components.

Part Context

This part belongs to the Lumissil IS31FL3726 family of LED drivers. The family includes variants with different packaging options, such as the QFN-24 (QFLS) and eTSSOP-24 (ZLS). These devices are designed for applications requiring multiple individually addressable LED channels with efficient linear regulation and digital control interfaces.

Replacement Considerations

The IS31FL3726A-QFLS4-TR is listed as a manufacturer-recommended alternative. Verify pinout and package compatibility between the eTSSOP-24 and QFN-24 variants before substitution.
