    IC for isolated power supply

    Witch ICS are most popular in commercial use SMPS?

    I need a DC/DC, 48V/48V (~30W) isolated power supply (flyback topology).

    Re: IC for isolated power supply

    I'm looking for a chip, not for a software.

    I think UC3843B is quite popular...

    Re: IC for isolated power supply

    I've been using these nice modules from Traco in my last designs.

    http://www.tracopower.com/products/dc-dc-converters/

    They offer good isolation, low parts count and is not so expensive. Take a look.

    For flyback topology, the UC384X series of controllers (UC3842, UC3843, UC3844, UC3845) is super popular. There are also other popular controllers such as MC34063. And then, based on such controllers, many more enhanced controller are also available, such as LT1241, for example.

    Hope this helps.
    Tahmid.
