AL9910A-5SP-13

Overview

The AL9910A-5SP-13 is a high-voltage PWM LED driver-controller from Diodes Incorporated, designed for offline constant-current LED lighting systems. It operates as an AC/DC offline switcher with a switching frequency of 300 kHz. The device supports input voltages ranging from 85 VAC to 277 VAC and handles DC bus voltages between 20 V and 500 V. It features a single output channel in an SOIC-8 package, suitable for buck, boost, or buck-boost topologies. Operating temperature ranges from -40°C to +105°C.

Feature Summary

• Integrated high-voltage startup circuit for simplified design
• Constant current regulation with dimming capability
• Built-in protection mechanisms including overvoltage and thermal shutdown

Applications

• Offline LED general lighting fixtures
• LED backlighting systems
• Signage applications

Procurement Notes

Verify the specific suffix '5' against the manufacturer's official datasheet to confirm voltage rating and pinout compatibility. Ensure the SOIC-8 package matches your PCB footprint requirements. Confirm RoHS compliance status through the latest component documentation before integration.

Selection Notes

Select this component for non-isolated LED drivers requiring wide input voltage range. Consider the 300 kHz frequency for component size optimization. Evaluate thermal performance within the -40°C to +105°C operating range for your enclosure design.

Part Context
