Product details

Description

The LTC®3672B-1 is a triple power supply composed of a 400mA synchronous buck regulator and two 150mA lowdropout linear regulators (LDOs), where one of the LDOs can be powered from the buck output to improve efﬁciency.

Constant-frequency 2.25MHz operation is maintained down to very light loads.
