Viper22a Circuit Diagram. Typical applications cover off line power supplies for battery charger adapters standby power supplies for tv or monitors auxiliary supplies for motor control etc. The circuit diagram is very easy to understand let s study it with the following points.
The input mains ac as usual is first rectified using ordinary 1n4007 diodes which is fixed in the bridge network mode. Led vu meter lm3914 lm3915 lm3916 led driver dot bar display made with a variety of integrated circuits vu meter circuit can use with normal 3mm leds 5mm leds as well as a bar have used modules are located in the meter has been deactivated.

By providing the design requirement info the complete power supply circuit diagram can be generated.
The mosfet is connected to the primary side a power transformer which when switched will produce the required output voltage based on transformer design. Sprint layout pcb file the prepared project with a well designed double sided pcbs used 4 integrated led bar. Also provides a charging current during start up. Before going straight into building the prototype part let s explore the circuitry operation.
