Overview
The IS31BL3508B-STLS2-TR is a single-output LED lighting driver IC from Lumissil Microsystems, featuring an integrated boost converter topology with an internal MOSFET. It operates within a supply voltage range of up to 5.5V and delivers a switch current of 1.2A at a switching frequency of 1MHz. The device supports both analog and PWM dimming methods for precise light control. Designed for surface mount installation, it utilizes a compact SOT-23-6 package. The component functions reliably across an ambient temperature range of -40°C to +85°C.
Feature Summary
- Integrates a step-up (boost) DC-DC converter with an internal power MOSFET for efficient LED driving.
- Supports flexible illumination control through combined analog and pulse-width modulation (PWM) dimming capabilities.
- Features a compact SOT-23-6 surface-mount package designed for space-constrained PCB layouts.
Applications
- LED backlighting systems
- General LED lighting applications
Procurement Notes
Verify the specific suffix STLS2 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm that the active status aligns with long-term availability needs, as automotive or industrial designs often require lifecycle stability assessments before finalizing component selection.
Selection Notes
Select this component when a single-channel boost driver with high efficiency and integrated switching elements is required. Ensure the input voltage does not exceed 5.5V and that the load current remains within the 1.2A switch limit. Verify compatibility with the desired dimming interface, whether analog voltage or digital PWM signals, prior to integration.
Part Context
This part belongs to the IS31BL3508B series of LED drivers. It shares the core boost converter architecture with variants like the IS31BL3508B-TTLS2-TR but differs in packaging and thermal specifications. The series targets cost-sensitive lighting solutions requiring minimal external components due to the integrated MOSFET design.
Replacement Considerations
The IS31BL3508B-TTLS2-TR is a related variant within the same product family. Verify package dimensions and thermal performance differences before substitution. No other direct cross-references are documented in public sources.
