TEA2095T application

[Dohko]

I would like to design a 500W power supply. Output 50V 10A.

May I know if I can use TEA2095T for the SR control? As I know, the supply voltage of TEA2095T is 38Vmax.  Then how can I provide suitable Vcc to TEA2095T. Because I have 50V output at the secondary side.

Hi Sam,

The TEA2095T can be used as the SR controller for a 50V/ 10A secondary, but you must supply its VCC from a separate supply (e.g. use an auxiliary transformer winding) that never exceeds its 38V limit. It cannot be powered directly from the 50V output.

BRs, Tomas
