Overview
The IS31BL3508A-STLS2-TR is an LED lighting driver IC manufactured by Lumissil Microsystems. It features a boost topology with an integrated MOSFET and supports PWM dimming. The device operates within an input voltage range of 2.7 V to 5.5 V and functions at a switching frequency of 1 MHz. It provides a maximum output voltage of 38 V and delivers a switch current of 1.6 A. The component is housed in a TSOT-23-6 package and is rated for operation between -40°C and +85°C.
Feature Summary
- Integrates a high-efficiency boost converter with an internal power MOSFET
- Supports precise PWM dimming control for LED brightness regulation
- Designed for compact applications due to small TSOT-23-6 packaging
Applications
- LED backlighting systems
- General LED illumination circuits
- Portable electronic device lighting
Procurement Notes
Verify the specific suffix STLS2 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the source document confirms the 38V output rating and 1.6A switch current limits. Check for any recent Product Change Notifications (PCNs) regarding package or material changes before finalizing procurement.
Selection Notes
Select this component when a compact, single-output boost driver is required for low-power LED applications. The integrated MOSFET simplifies the bill of materials compared to discrete solutions. Verify that the 1.6A peak current capability meets the load requirements and that the 1 MHz switching frequency aligns with passive component selection constraints.
Part Context
This part belongs to the IS31BL series of LED drivers from Lumissil Microsystems, which focuses on efficient power management for lighting applications. The BL series typically utilizes boost topologies to drive LEDs from lower supply voltages. The STLS2 suffix indicates the specific tape-and-reel packaging configuration for automated assembly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Lumissil Microsystems directly for qualified alternatives or cross-reference options based on specific electrical parameters.
