This dual-channel constant-frequency, constant-current/constant-voltage (CC/CV) boost power stage controller is 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.
The device is offered in a side solderable 4.0 mm × 5.0 mm QFN-28 package and is AEC-Q100 qualified for automotive applications.
Typical applications for the LT8355-1 include high-voltage LED applications, automotive headlamps and running lamps and current-limited voltage regulators.
