Sample 5W Switch Mode Power Supply Using TOPSWITCH


The following ( Figure 1) is a schematic of a 5 watts switch mode power supply design using Power Integration TOPSWITCH part number: TOP200YAI. The schematic shows an input 10mH common mode choke ( availabe from CWS), and a power transformer with CWS part number: TS200Y02.

This circuit has an absolute minimum part count for a 5Vout, 5W isolated bias supply. The input voltage is universal AC input. Isolated bias supply is common called the house keeping power supply to power the IC chips in the main power supply.
