AL5809-150P1-7

Overview

The AL5809-150P1-7 is a linear LED driver IC from Diodes Incorporated, designed for constant current regulation in lighting applications. It operates within an input voltage range of 2.5 V to 60 V and delivers a fixed output current of 150 mA. The device supports PWM dimming with a frequency range of 100 Hz to 200 Hz and withstands up to 60 V output voltage. Packaged in a compact PowerDI-123-2 surface-mount format, it functions across a temperature range of -40 °C to +125 °C.

Feature Summary

• Provides stable constant current regulation for single-channel LED loads
• Enables precise brightness control through integrated PWM dimming capability
• Operates reliably under wide input voltage conditions without external switching components

Applications

• General solid-state lighting fixtures
• LED backlighting systems
• Automotive interior illumination modules

Procurement Notes

Verify the specific suffix P1-7 against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with AEC-Q100 automotive standards if required for your application. Cross-reference datasheet revisions to validate thermal performance parameters before finalizing procurement orders.

Selection Notes

Select this component when a simple linear solution is preferred over complex switching regulators for low-to-medium power LED strings. The fixed 150 mA output suits applications requiring consistent brightness without adjustable current settings. Consider the PowerDI-123-2 footprint constraints during PCB layout planning to ensure adequate thermal dissipation for continuous operation.

Part Context

This part belongs to the AL5809 series of two-terminal LED drivers. Unlike traditional three-terminal regulators, these devices simplify circuit design by integrating control logic into a minimal pin-count package. The series offers various current options to accommodate different LED power requirements while maintaining high efficiency in linear topologies.

Replacement Considerations

Check for exact current rating matches (150 mA) and identical PowerDI-123-2 packaging when sourcing substitutes. Verify that alternative parts support the same 60 V maximum voltage and PWM dimming frequencies to maintain system functionality without redesign.
