Tinyswitch 4 with 400VDC input?
Posted by: treez

Hi,
We want to do a 20W Flyback (15Vout) using Tinyswitch4. The input will be the output of the PFC stage, ie 400VDC.....do you think this will be OK,
or will the 400V cause too much switching loss?
Hi treez,
Happy new year! Thank you for your continuous support to Power Integrations solutions.
Yes, the TinySwitch-4 can be used in application of 400 VDC input and 15 V output. We've made an initial design from our PI Expert Online tool that is accessible in this link: https://piexpertonline.power.com/fileManager/index?shared=91547322245458d3ba7b54e265315da86d8a3904dc70d20b0eeaf2b2b0bf953f
We have RDR-295 you can check for efficiency performance with high VDC input and same power level.
I hope this works for you.
