LT8355-1 Datasheet Dual Led Controller

Manufacturer: Analog Devices

Overview: LT8355-1 60VIN/120VOUT Dual LED Controller with Exponential PWM and Scalable.

Datasheet Details

The LT®8355-1 a dual-channel DC/DC controller designed to drive two strings of high current LEDs.

The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages.

Voltage feedback pins serve as the inputs for several LED protection
