Other Parts Discussed in Thread: UCC28C45

Hi,

One of my customers in Australia is looking for a Single DC-DC Converter which can provide the following:

Vin: 6.6V-7.2V, Vout1: 5V, Iout1: 2A

Vin: 11V-14V, Vout2: 7.2V, Iout2: 1A

Is there any suitable single part that can help or will the solution need two DC-DC regulators. Please help me with the part number.

Hi Rajatshuvra.

Why don't you think to a single stage flyback with 6.6-14V input voltage range?

You can easily obtain both outputs and if you need a very high precision you can always regulate the 5V output and for the second one you can regulate something more than 7.2V and use an adjustable linear regulator to obtain your target...
It's not an high efficiency solution, but it could solve your problem...

Bye

Can you suggest any part number which will be most suitable and also price competitive. Target pricing is in the range of $0.6

Hi Rajatshuvra.

Try to have a look to the UCC28C45...

It seems to match your criteria and it is very suitable for the application.

Bye
