  • Choosing a SMPS controller IC

    Hi,

    I'm looking to design/build a SMPS for a home project and therefor needs to use components that can be hand solder. I've been looking at a few different manufactures and I'm trying to work out which device or devices would be best suited to my needs.

    My basic design goals are to use 230Vac 50hz Input and produce 2 output voltages ( 5V @ 13A and 3.3V @ 10A ) the max current values can vary a little if design requires it. I'd alike to be able to simulate the design in LTspice to help verify the design before building.

    I've looked at the following manufactures:

    Power Integration, there Topswitch family appears to have some good documentation and design tools but I haven't been able to find any SPICE models which prevents simulating the design in something like LTSpice.

    Linear Technology, something like the LT3748 but fear that this will not be suitable for hand soldering. The documentation and design tools make it a little harder to find the most suitable devices.

    OnSemi, Something like the NCP1380, once again fear it will not be suitable for hand soldering. The documentation and design tools make it a little harder to find the most suitable devices, but at least the do appear to have a number of Spice models.

    I have found that there appears to be enough information available to determine the component values and transformer requirements regardless of which device I choose, although some are easier to work with than others.

    Can anybody recommend which devices might be most suitable to my needs.

    Thanks
