Other Parts Discussed in Thread: LM2577

DC / DC design requirements, VIN = 18V ~ 36V, Vout 10W / 24V, INTEGRATIONS POWER DPA423 is now used. Is there any product recommendation that Ti can replace dpa423?

Hi Zhang,

Thanks for reaching out with your question and for considering TI.

For your application does the output voltage need to be isolated?

Thanks,

Garrett

Integrated MOSFET and PWM controller, flyback circuit or forward circuit. The picture below shows the forward application of dpa423. Dpa423 is suitable for application, but there are few agent channels. It is hoped that Ti has alternative materials.

Hello Zhang

The LM2577 would work for this application.

Thanks,
