SMPS DESIGN FOR 12V 250 mA 24V 250 mA , -8v 10 mA suitable for 450V input AC supply

Posted by: govind-kataria on 04/13/2011

I need to design a smps which can work within AC input voltage of 150-450 V . The output power is maximum 9.08 Watts. Can I base my design using Tiny Switch III series and a Mosfet IRF 840 in series with the inner MOSFET of the device (TNY SwitchIII) as suggested in your design for high input (three phase input around 500V AC). What special precautions need to be followed in designing this supply?

Hello,

We are using LNK603 device for a new design with two isolated outputs 5V@ 150mA and 5V@250mA.

How do I add a second output in the PIXls design ?

Thanks

The LinkSwitch-II PIXls designer does not support multiple outputs. Consider using the LinkSwitch-CV as a solution.c
