Product Overview

The LM3463EVM is an evaluation module for LM3463, a six channel linear LED driver with dynamic headroom control designed to drive six strings of high brightness LEDs. Each output channel of the LM3463 evaluation board is designed to deliver 200mA of LED driving current. The LED turn on voltage is set to 48V by default, thus the board is able to deliver up to 57.6W total output power. The six output channels are divided into 4 individual groups to facilitate average LED current control by means of PWM dimming. The PWM dimming control interface of the LM3463 can accept standard TTL level PWM signals, analog voltage or serial data to control the dimming duty of the four LED groups individually. The analog dimming control interface accepts an analog control voltage in the range from 0V to 2.5V to adjust the reference voltage of the linear current regulators, which enables true LED current adjustment. This evaluation board is designed to be connected to an external primary power supply.
  • Input voltage range from 12V to 95V
