5 volts DC Regulator Without Transformer Using MOSFET
Power supply
This is 5 volts DC Regulator power supply that without the transformer so small size, use the MOSFET is based. It is suitable the digital circuit. Caution! This circuit requires very careful to create. Because there is a high voltages many areas. The diodes D1 to D4 are used to convert AC power line to DC pulse voltage that have the peak is 310 volts. Then, apply to the drain of the MOSFET T1 by through the limit current resistor-R9. The controller circuit causes the MOSFET works briefly only, Before and after power cut at zero volts. In this time …
