LT8357EMSE#PBF

LT8357 is a wide input range, current mode, DC/DC controller which can be configured as a boost, SEPIC or flyback converter. This device 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. It provides a simple, compact and efficient solution for automotive, industrial, and battery-powered systems. It is widely used in application such as automotive and industrial systems, battery-powered systems, portable electronic equipment etc.
