Краткое описание:
N-channel Controller for Constant-Current LED Drivers with Output Status Flag
Дополнительная информация
The LM3423 is a versatile high voltage N-channel MOSFET controller for LED drivers that can be easily configured in buck, boost, buck-boost, and SEPIC topologies. It features an input voltage range from 4.5V to 75V and uses predictive off-time (PRO) control. The device includes a high-side adjustable current sense, a 2-Ω/1-A peak MOSFET gate driver, and specialized features such as a LED output status flag and a fault status flag with a timer.
