30W Power Supply Circuits Sample


Sample 30W Power Supply Circuits using TOPSWITCH


The following (Figure 3) is a schematic of a universal AC input, 15Vout, 30W power supply using Power Integration's TOP204YAI chip. All the magnetics, L1, L2 and T1 ( TS204Y02) are available from CWS.

This circuit features an improved output voltage accuracy and regulation with optically coupled feedback control.
