The shows a classic buck converter: The internal MOSFET switches at ~150kHz, dumping energy into L1 (33µH – 47µH) . During the off-time, current flows through D2 (SS54) . The output capacitor C3 (220µF) filters the result.
YP-05 Schematic is a specific technical drawing typically used in the design and documentation of hydraulic services and water supply systems , specifically within the context of fire protection. Yp-05 Schematic
Use free software like EasyEDA or KiCad. Start with the IC, add input caps, output caps, inductor, diode, and feedback network. You now have a working ready for simulation. The shows a classic buck converter: The internal
