Viper12a Smps Circuit Diagram. Vıper12 the vıper22 non isolated power supply desinger st microelectronics firm viper from the series viper12 viper22 integrated prepare for the non insulated smps power supply design program especially white leds power leds to run the various circuits can be designed or over current uninteresting to any circuit feeds used in the core of the transformer coil is used instead of the. The controller can convert ac voltage from 85v to 265v and convert it to regulated dc voltage with a maximum output current of 200ma it is commonly used as a replacement for transformerless power supply circuits.
A 3 phase 4 wire bridge is used for mains rectification because the neutral rectification is needed to ensure proper operation in case of missing neutral connection or neutral mis wiring. Have a nice design sizes quite small. The mosfet is connected to the primary side a power transformer which when switched will produce the required output voltage based on transformer design.

The circuit uses negligible number of external components yet is able to operate directly from mains ac input. Stmicroelectronics alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated circuits diodes triacs and other semiconductors. Looking at the given circuit diagram we see that the input stage incorporates a surge limiting resistor which quite acts like a fuse a diode for rectifying the ac and an lc filter network for further filtration of the dc riples. The controller can convert ac voltage from 85v to 265v and convert it to regulated dc voltage with a maximum output current of 200ma it is commonly used as a replacement for transformerless power supply circuits.
