LT3477 Datasheet (Linear Technology)

LT3477, DC/DC Converter

The LT®3477 is a current mode, 3A DC/DC step-up converter with dual rail-to-rail current sense amplifiers and an internal 3A, 42V switch.

It combines a traditional voltage feedback loop and two unique current feedback loops to operate as a constant-current, constant-voltage source.

Both current sens
