Altair04-900

is it possible to get output power 120w using altair04-900 flyback converter method

[Peter BENSCH]

No, that requires a more powerful converter device.

Thank you for your reply sir, any other power converter available in ST that can give 120W output and that can support input voltages upto 440VAC (622vdc) .

is there any software tool available for design a flyback transformer in ST

[Peter BENSCH]

The power class is difficult to achieve with integrated switches, and additionally optimum efficiency for 120W is achieved with a quasi-resonant converter instead of a flyback.

You could take a look at the L6566BH, which is designed for 3-phase applications, but can only handle a maximum of 840V instead of 900V (ALTAIR04-900). You can dimension and simulate the design with the online tool eDesignSuite (select Power Supply Design Tool > AC/DC), but it assumes an ideal transformer and cannot calculate it. However, transformer manufacturers should be able to help you with this.

Good luck!
