The FSEZ1307 is a low-power PWM controller with integrated power MOSFET from Fairchild Semiconductor Corporation. It features low standby power, high voltage startup, few external components, constant voltage (CV) and constant current (CC) control without secondary-feedback circuitry.
The FSEZ1307 is a third-generation Primary Side Regulation (PSR) PWM controller combination power MOSFET designed to enhance the performance of low-power flyback converters. It features proprietary TRUECURRENT technology for precise constant-current regulation and simplified circuit design, particularly suitable for battery charger applications. The device minimizes standby power consumption through a proprietary Green Mode that linearly decreases PWM frequency under light-load conditions.
