AS1113-BSST

Overview

The AS1113-BSST is a single-channel LED driver IC manufactured by ams OSRAM, designed for high-performance lighting applications. It features an integrated power switch capable of delivering up to 2 A of continuous output current with low on-resistance. The device supports PWM dimming frequencies ranging from 1 kHz to 500 kHz and includes thermal shutdown protection. Operating voltage ranges from 4.5 V to 36 V, housed in a compact SSOP-28 package suitable for surface mount assembly.

Feature Summary

Integrated high-current power switch for direct LED driving
Wide input voltage range supporting various supply configurations
High-frequency PWM dimming capability for flicker-free operation
Built-in thermal shutdown for enhanced system reliability

Applications

Automotive exterior lighting systems
Industrial machine vision illumination
Medical diagnostic equipment lighting
High-brightness general lighting fixtures

Procurement Notes

Verify the specific suffix 'BSST' against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the selected component meets the required automotive or industrial qualification standards if applicable to your design. Cross-reference the ordering code with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a single channel requires high current handling without external MOSFETs. Consider the thermal performance of the SSOP-28 package under maximum load conditions. Evaluate the PWM frequency requirements against the application's visual or sensing constraints. Verify input voltage stability within the 4.5 V to 36 V operational window.

Part Context

This part belongs to the AS111x family of single-channel LED drivers from ams OSRAM. These devices are engineered for robustness in demanding environments, combining control logic with power delivery. The series is widely used in applications requiring precise current regulation and efficient thermal management within a compact footprint.
