A compact, robust power supply for hobby PCBs:

When working with these boards, be aware that the (AC input section) contains high voltages (typically ~310VDC after rectification). Always use a proper ground for measurements and ensure capacitors are fully discharged before handling. wannien 101v0 power supply schematic free

An integrated circuit (IC) that controls the switching frequency of the power MOSFET.

: "No power" or "no display" symptoms are frequently caused by bulging or leaked electrolytic capacitors. If you are looking to fix a specific

The board uses a standard layout of resistors, capacitors, transistors, and integrated circuits, which can be identified in the diagram. Where to Find the Wannien 101V0 Schematic Free

Look for an 8-pin DIP or SOT-23-6 chip near the MOSFET. An integrated circuit (IC) that controls the switching

: Search for the service manual of the specific monitor brand (e.g., HP, Dell, or ViewSonic) that contains the board. Component Datasheets

It utilizes four distinct transistor switch circuits (often labeled out1 through out4 ) to control output loads.

If you are reading this, you likely have a dusty Wannien 101v0 bench power supply sitting on your workbench—either non-functional or in the middle of a repair project. Alternatively, you might be a hobbyist looking to reverse-engineer this classic, budget-friendly linear power supply for a custom build.
