LM3423 N-Channel Controllers

The LM3421 and LM3423 family of devices are versatile high voltage N-channel MOSFET controllers for LED drivers. They can be easily configured in buck, boost, buck-boost and SEPIC topologies. This flexibility, along with an input voltage rating of 75 V, makes the these controllers ideal for illumina.

LM3423 Features

* 1 VIN Range From 4.5 V to 75 V

* High-Side Adjustable Current Sense

* 2-Ω, 1-A Peak MOSFET Gate Driver

* Input Undervoltage and Output Overvoltage Protection

* PWM and Analog Dimming

* Cycle-by-Cycle Current Limit

* Programmable Switching Freq
