IS32LT3124C-ZLA3-TR

Overview

The IS32LT3124C-ZLA3-TR is a single-channel linear LED driver IC manufactured by Lumissil Microsystems. It provides a regulated output current of up to 600mA with an operating supply voltage range from 5V to 28V. The device integrates PWM dimming control and features dynamic headroom control (DHC) for optimized efficiency. It is housed in a 16-pin eTSSOP package with exposed pad, supporting surface-mount assembly.

Feature Summary

Integrates dynamic headroom control (DHC) to optimize power dissipation across channels
Supports one-fail-all-fail fault reporting with auto-recover functionality
Includes integrated PWM dimming control for precise brightness adjustment

Applications

Commercial general lighting fixtures
Residential LED downlights
Automotive interior illumination systems

Procurement Notes

Verify the specific suffix ZLA3 against the manufacturer's latest datasheet to confirm pinout and thermal specifications. Confirm RoHS compliance status as required by your assembly process. Check for any Product Change Notifications (PCN) issued after the original datasheet publication date to ensure material consistency.

Selection Notes

Select this component when a single high-current channel is required with integrated protection features. The DHC feature makes it suitable for designs where thermal management is critical. Ensure the input voltage does not exceed the 28V maximum rating during transient conditions.

Part Context

This part belongs to the IS32LT31xx series of linear LED drivers from Lumissil. Unlike multi-channel variants such as the IS32LT3124B, this specific model focuses on single-channel performance with advanced fault handling. It complements the broader portfolio designed for monolithic-based solutions in general lighting markets.

Replacement Considerations

The IS32LT3124B-ZLA3-TR is a related quad-channel variant within the same family but differs in channel count and pin configuration. Direct substitution requires verifying that the application design accommodates the difference between single and quad-channel architectures.
