Description

General part information

LT8357 Series

The LT8357 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. At light load, either pulse-skipping mode or low-ripple Burst Mode operation can be selected. Additional features include output power good and output short circuit protection in SEPIC and flyback configurations.With a wide 3V to 60V input voltage range and 8μA low quiescent current, the LT8357 provides a simple, compact and efficient solution for automotive, industrial, and battery-powered systems.APPLICATIONSAutomotive and Industrial SystemsBattery-Powered SystemsPortable Electronic Equipment
