IC for isolated power supply

[tantudaisu]

Witch ICS are most popular in commercial use SMPS?

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

Use PI expert spftware & it's IC for SMPS

 

[tantudaisu]

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

I think UC3843B is quite popular...

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

**broken link removed**

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.

Please Give me the input specification i will give you the complete design.

What i mean to say that, Please tell me the input voltage.
If you need design for 48V to 48V why you need the design.

 

[tantudaisu]

input voltage is 36-58V

you need something like this http://danyk.cz/univ_m_en.html but modified for 36-58 input
