Description
The UCC3960 primary-side startup controller is a unique solution that provides all the primary-side functions required for a single-ended, isolated offline, switch-mode power converter that uses secondary-side PWM control.
Features
- such as output current sharing and synchronous rectification are implemented more easily. The UCC3960 provides all the circuitry required on the primary side of a secondary.
- side controlled power supply. It features a free running 60-kHz to 360-kHz oscillator that is synchronizable to the secondary-side PWM signal and also has the ability to accept start/stop PWM commands from the isolating pulse edge transformer. The use of an extremely small and low-cost pulse transformer allows for hig.
