Description

Figure 1 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.It is usable with a wide range of secondary circuits and is especially well suitable for systems where sophisticated handling of overload conditions is required.Secondary-side control assumes that output voltage and current measurements are interfaced directly to

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.
