Component Selection & BOM

Lena knew the 101v0 was a workhorse—a switch-mode unit popular for its compact 10A output and adjustable voltage. But without a schematic, repair was guesswork. She pulled up a —a community-sourced, redrawn version of the original messy diagram. It was color-coded and reorganized into logical blocks: EMI filter, primary rectifier, PWM controller (UC3842), switching MOSFET, high-frequency transformer, secondary rectifiers, feedback optocoupler, and output regulation (TL431).
