1.3 W Switch Mode Power Supply Using TINYSWITCH
 

"We will wind anything for you"

If you can conceptualize it, draw it, sketch it or describe it, we can wind it for you. Of course, if you have an engineering print of it, we can serve you even better.



The following is a sample circuit of a 1.3 watt, 7.5Vout TV Standby switch mode power supply using Power Integration's TINYSWITCH. The TINYSWITCH part number is: TNY253P.

CWS supplies the 15 uH output choke (L1) and the main power transformer, T1. CWS' part number for T1 is: TN253P00.

This power supply generates an insolated 7.5vdc output from a high voltage DC input ( 120 to 375Vdc). This circuit is desigend to replace a linaer type power supply or a self osciallating ringing choke converter (RCC) at a lower cot, and lower component counts.

This circuit shows that it is possible to design a lower cost alternative to linear type power supply with the advantage of a much smaller szie.
