LT8355-1 Dual LED Controller with Scalable Dimming

Analog Devices Inc. LT8355-1 Dual LED Controller is a dual-channel constant-frequency, constant-current/constant-voltage (CC/CV) boost power stage controller designed to drive two strings of high-current LEDs. The fixed frequency, current mode architecture of the LT8355-1 results in stable operation over a wide range of supply and output voltages. Voltage feedback pins serve as the inputs for several LED protection features and make it possible for the converters to operate as constant-voltage sources.
