Description: Constant Current N-Channel Controller

Features

* include slope compensation, softstart, over-voltage and under-voltage lock-out, cycle-by-cycle current limit, and thermal shutdown. Features
* VIN range from 4.5V to 75V High-side adjustable current sense 2Ω, 1A Peak MosFET gate

Applications

* Adjustable high-side current sense voltage allows for tight regulation of the LED current with the highest efficiency possible. The LM3424 uses standard peak current-mode control providing inherent input voltage feed-forward compensation for better noise immunity. It is designed to provide accurate
