TNY288DG Auto- restart

2 posts / 0 new

Hi,

We are using TNY288DG switcher in our high power design project. The specifications are as follows:

Vin: 312- 530 Vrms
Vout1: 24 VDC @ 50 mA
Vout2: 5V DC @ 1A

Auxiliary Winding: 15V @ 100mA (4-5)

The switcher is going to auto restart mode after switch on and it is not recovering back. Please help us on the same.
Attached schematic and transformer design for reference.

Regards
Shwetha
