FSBH0270-F116 - Fairchild Semiconductor

FSBH0270-F116 Green Mode Fairchild Power Switch

The highly integrated FSBH-series consists of an integrated current-mode Pulse Width Modulator (PWM) and an avalanche-rugged 700 V SenseFET. It is specifically designed for high-performance offline Switched-Mode Power Supplies (SMPS) with minimal external components. The integrated PWM controller features include a proprietary green-mode function that provid.
