LT8357 Boost, SEPIC & Flyback Controllers

Analog Devices LT8357 Boost, SEPIC & Flyback Controllers are 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 a 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.
