LT8357 Datasheet Sepic And Flyback Controller

Manufacturer: Analog Devices

Overview: LT8357 60V 2MHz Low-IQ Boost, SEPIC and Flyback Controller.

General Description

The LT®8357 is a wide input range, current mode, DC/DC controller which can be configured as a boost, SEPIC or flyback converter.

The LT8357 drives a low side N-channel power MOSFET with 5V split gate drive.

The current mode architecture allows adjustable and synchronizable 100kHz to 2MHz fixed frequency operation, or internal 19% triangle spread spectrum operation for low EMI.
