Littelfuse, Inc. has announced the launch of the 5.0SMDJ-FB TVS Diode Series, a 5,000 W surface-mount solution in a DO-214AB ...

The Littelfuse 5.0SMDJ-FB TVS diodes in a compact package deliver advanced protection from transient voltages.

Thus an AC voltage applied to C1 will appear at both the anode and cathode of the diode, and will make it through C2 to the output. The switch has been turned ON.

The input voltage is 100V. The secondary voltage is 20V at a mean current of 5A. The frequency is to be 50 kHz, with a 50% ON period for Q1 (10µs).

TI’s LM74670-Q1 is a controller that, combined with an n-channel mosfet, makes a diode with a forward drop of 20mV 98% of the time. It only connects to the mosfet (and a capacitor) and not to any ...
