IS31BL3232-DLS2-TR

Overview

The IS31BL3232-DLS2-TR is an LED driver IC manufactured by Lumissil Microsystems, classified as a DC/DC regulator with switched capacitor (charge pump) topology. It features one output capable of delivering up to 1.2A and includes internal switches. The device is housed in a 10-DFN package and operates within a standard commercial temperature range.

Feature Summary

Integrates a charge pump topology for efficient voltage regulation
Provides high-current single-channel output capability
Includes internal switching components to reduce external component count

Applications

Industrial systems requiring regulated LED power
Consumer electronics backlighting solutions
Digital system illumination control

Procurement Notes

Verify the specific suffix DLS2 against the manufacturer's current datasheet to confirm pinout and thermal specifications. Ensure the 10-DFN package footprint matches the PCB design. Confirm RoHS3 compliance status if required by local regulations. Cross-reference the active part status with official distributor channels to avoid obsolete stock.

Selection Notes

Select this component when a single-channel, high-current LED drive solution is needed without external inductors. The charge pump topology simplifies board layout compared to inductive regulators. Verify that the 1.2A output current meets the load requirements and that the 10-DFN package fits the available space constraints.

Part Context

This part belongs to Lumissil's LED driver portfolio, designed for regulated lighting applications. It complements other drivers like the IS31BL3230 series but offers distinct packaging and current capabilities. The product line targets cost-sensitive consumer and industrial markets requiring reliable LED regulation.
