AL8400QSE-7 Description

Short technical summary and product information.

The Diodes Incorporated AL8400QSE-7 is an adjustable linear LED driver-controller designed for efficient LED current regulation. It features a low 200mV current sense voltage (FB pin), minimizing power dissipation and making it suitable for medium to high current LED applications. The open-collector output can operate from 0.2V to 18V, enabling the use of external MOSFETs or bipolar transistors for optimized performance.

 

This device offers excellent temperature stability with an operating temperature range of -40°C to +125°C and a reference voltage tolerance of 3% at +25°C. It boasts high power supply rejection of over 45dB at 300kHz. The AL8400QSE-7 is Automotive Grade qualified to AEC-Q100 Grade 1.

 

Available in the space-saving SOT-353 package, the AL8400QSE-7 is ideal for applications such as isolated offline LED lamps, linear LED drivers, LED signs, and instrumentation illumination. It is manufactured with a lead-free finish and is RoHS compliant, also being halogen and antimony-free.

 

Key electrical characteristics include a low reference voltage of 0.2V and an output voltage range of 0.2V to 18V. The device is designed for surface mount applications.
