Fairchild FSL1x7 Power Switch Application for Low-Power Supplies
The document describes the Fairchild FSL series, a high-integration PWM controller designed for offline switch-mode power supplies (SMPS). Key features include a current-mode control with avalanche-rated 700V sense FBT, a Green Mode function that linearly reduces switching frequency under light loads to minimize standby power, and a proprietary line correction circuit for wide AC input ranges. This manual is written in Japanese.
