High Power SMPS for Battery Charging

Posted by: katte swaminath on

Hello,

I am going to design a SMPS for battery charging with below given specification. Please suggest suitable PI part and design guide for the same.

AC Input Voltage Range 170-300VAC
Ac Input Voltage Nominal- 230VAC
AC Input Frequency 47-53Hz

DC Output Voltage - 65V +/- 0.5V
DC Output Line and Load Regulation - +/- 2%
Protections- Over load , Output Short Circuit, Over Temperature, Battery reverse, Boost Charging Safety timer,

Thanks and Regards,
Swaminath

10VDC and 3 amp is 30 watts out, not 20. There appear to be many design solutions listed on the PI website ...

Hi Ravi,

Just to clarify, you are designing a 20W and not a 30W SMPS right? For a 20W design you may try TOPSWITCH family of IC. For 85VAC-265VAC input voltage, you can can consider TOP258PN. Below is the link for the datasheet:

For a reference design you may check the following link:

Now , in order to cater for your particular specs and design you may want to try our design tool in the following link:

By the way what application are you targeting for this design? Thank you very much.
