LT3757A - SEPIC and Inverting Controller

Download the LT3757A datasheet PDF. This datasheet also covers the LT3757 variant, as both devices belong to the same sepic and inverting controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LT®3757/LT3757A are wide input range, current mode, DC/DC controllers which are capable of generating either positive or negative output voltages.

They can be configured as either a boost, flyback, SEPIC or inverting converter.
