60W 16V SMPS Evaluation Board with F3 controller ICE3BS03LJG Universal input power supply designed in a 16V 60W off line flyback converter that utilizes the F3 controllerICE3BS03LJG. The application board is operated in discontinuous current mode and running at 65 kHz switching frequency. It has one output voltage with secondary side control regulation. The ICE3BS03LJG is a current mode PWM controller. With the 500V startup cell, active burst mode and BiCMOS technologies, the standby power can be <100mW at no load. The frequency jitter mode and the soft gate drive can give a low EMI performance. The built-in 20ms blanking window and the extendable blanking time concept can prevent the IC from entering the auto restart mode due to over load protection unintentionally. The outstanding propagation delay compensation feature can allow a very precise current limit between low line and high line. For this IC, it provides both auto-restart and latch off protection mode. For those serious faults such as Vcc over-voltage, over temperature, short transformer winding, etc, the IC will enter the latched off protection mode. For the less severe case such as the over load, open loop, short opto-coupler, etc, it enter the auto restart protection mode. In case it needs customer defined protection, the external latch off enable feature can fulfill the requirement.
