Hi,
I am searching for a IC which can take 42-48V & 7A input and give the same for switching. Can someone suggest something regarding this

 

I assume you are looking for a controller solution for a power
supply, one that delivers 7A out at 42 - 48 volts ?

Regards, Dana.

Thank you for the response...
yes.. i tried relay switching but it is very slow. I am looking for a fast switching. The switching should happen in 10ms

 

What is load ?

In general one thinks of MOSFET or IGBT, maybe isolation, followed by a
gate driver.

Thank you for the suggestion. I already tried MOSFET it was some what ok for the output which i am looking for now i will try IGBT. Input 48V & 7A and output required is also same but switching action should happen in 10ms.

What's "some what ok".
A properly configured MOSFET should perform the switching task without problem.

Post the circuit you tried.

The switching action is ok but the speed i am looking for that point i am speaking

 

Of course, if you show your scheme, it will help.
But I have specific questions:
1. What is the source of control signal?
2. Is the load grounded?
3. What is the load.
Give advice: IGBT is good for high voltages.Tell me: do you feel sorry for losing 1.5 -2 volts on an IGBT transistor?

I don't understand.
Do you mean it switches too slowly or too fast?

i need faster than that

 

Solid state relay?

 

i need faster than that

A properly configured and driven MOSFET can switch in less than a microsecond.

Thank You. I will check
