24 Volt 10 Amp power supply using L6566B (Multi-mode controller for SMPS)

Hello St community,

I am designing a 24 Volt 10 amp power supply. Could you please review this design.

1. Transformer leakege value 1.84 µH may be difficult in order to be manufacturing. If possible, increase this value. This means you have to reduce the ac input voltage range.

2. Although it is not explicitly stated in the schematics diagram, do not forget to connect a capacitor (2200 pF) between grounds.

Good luck.

Thankyou EDokm,

could you please  MOSFET part number & transformer turns & inductance. I am using EE4215 core.

We are using IPAN80R280P7 MOSFET. Our transformer specs are given in the attached pdf. We had this transformer produced by a local Turkish company.

Regards.
