illustrate

The LM3421/23 are versatile high voltage LED driver N-channel MOSFET controllers. They can be easily configured in buck, boost, buck-boost and SEPIC topologies. This flexibility, along with a 75V rated input voltage, makes the LM3421/23 ideal for a large number of home lighting applications.

Adjustable high-side current sense voltage maximizes the efficiency of tightly regulated LED current. The LM3421/23 uses the Predicted Off-Time (Pro) Control, which is a combination of peak current mode control and a predictive shutdown timer. This control method simplifies loop compensation design while providing inherent input voltage feedforward compensation.

The LM3421/23 unit includes a high voltage start-up regulator over a wide input voltage range of 4.5V to 75V. The adjustable switching frequency up to 2.0 MHz is designed with an internal PWM controller, resulting in a compact solution. Other features include "zero current" shutdown, analog dimming, PWM dimming, overvoltage protection, undervoltage lockout, cycle-by-cycle current limit, and thermal shutdown.

The LM3423 also includes LED output status flags, fault flags, a programmable fault timer, and logic inputs to select the polarity of the dimmed output driver.

LM3421Q1/23Q1 is AEC - Q100 Standard Class 1 qualified, LM3421Q0/23Q0 AEC - Q100 Standard Class 0 qualified.
