How to easily convert +28V to +33V supply ?

[djnik1362]

hi
We have a +28V supply in our system and we need a single +33V
in our circuit . Is there any simple solution that we use to provide
desired voltage ?

thanks.

Yup. Design a boost converter to boost the 28V to 33V.

Hi djnik1362,

Is this SMPS?if there is a trimpot for trimming the output,you can adjust it by turning the trimpot then measure the output voltage.Some SMPS has a trimpot to trim the output.

I want to use ready-to-use device .
I can't design any supply.

how much current you need?

i don't know. What the SMPS is ?

SMPS = Switchmode Power Supply

how much current you need?

about 1.0 Amps.

thanks but i want to use devices such a step-up DC/DC converter.
i can't design any supply.

They will help you to design. Web based.

@djnik1362

do you have schematics about your PSU?
Is is the 28V output comes from SMPS?If yes you can provide schematics so that i can help you to modify it from 28V to 33V.Since it is only increase with 5V the voltage divider reference can be trimmable.
