AL9901S16-13

Overview

The AL9901S16-13 is a high-voltage LED driver IC from Diodes Incorporated, designed for offline applications. It operates within an input voltage range of 20 V to 500 V and delivers a constant output current of 400 mA. The device utilizes a buck topology with a fixed switching frequency of 120 kHz. It supports PWM dimming capabilities and functions reliably across a temperature range of -40°C to +125°C. Packaged in an SOIC-16 format, it serves as a universal driver for LED lighting systems.

Feature Summary

• Supports PWM dimming control for adjustable brightness levels
• Provides constant current output regulation for stable LED performance
• Operates directly from high-voltage offline AC/DC sources

Applications

• Offline LED lighting fixtures
• General illumination systems requiring high voltage input
• LED drivers utilizing buck topology

Procurement Notes

Verify the specific suffix '13' corresponds to the required tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the SOIC-16 footprint matches the target PCB design constraints. Cross-reference thermal requirements against the specified operating temperature range.

Selection Notes

Select this component when designing circuits that require direct connection to high-voltage mains without intermediate isolation stages. The integrated buck converter simplifies schematic design by reducing external component count. Consider the 400 mA output limit when sizing LED arrays. The wide input voltage range accommodates global line voltage variations effectively.
