IS31BL3231-DLS2-TR

Overview

The IS31BL3231-DLS2-TR is a programmable LED driver IC manufactured by Lumissil Microsystems, designed for general lighting applications. It features an integrated power MOSFET capable of delivering up to 750mA output current with a maximum voltage rating of 40V. The device supports switch dimming functionality and is housed in a compact 10-WFDFN package with an exposed pad. It operates within a supply voltage range of 2.3V to 5.5V and is rated for industrial temperature ranges.

Feature Summary

Integrates a high-side power MOSFET for monolithic LED driving solutions
Supports switch dimming control interface for external switching inputs
Programmable architecture allows customization for various lighting profiles

Applications

General commercial and residential LED lighting fixtures
Battery-powered portable lighting devices
Automotive interior and exterior illumination systems

Procurement Notes

Verify the specific ordering suffix DLS2 against the manufacturer's latest datasheet to ensure correct pinout and thermal pad configuration. Confirm RoHS3 compliance status and moisture sensitivity level (MSL) requirements prior to PCB assembly planning. Check for alternative packages if board space constraints differ from the standard 10-WFDFN footprint.

Selection Notes

Select this component when a single-chip solution integrating both driver and power switch is required to minimize external component count. It is suitable for designs prioritizing thermal efficiency and simplified bill of materials over complex multi-channel matrix addressing. Ensure the load current does not exceed the 750mA continuous limit under worst-case thermal conditions.

Part Context

This part belongs to Lumissil's H-BL-E-D drivers portfolio, which targets general lighting markets with monolithic-based solutions. The series offers flexibility in design through programmable parameters while providing built-in protections for extended-life operation. It complements the company's broader range of controller-based and linear LED driver products.
