DC-DC design how to 1

[cmb042]

I want to learn how to design a low noise, low current, high temperature, DC-DC HV power supply. Anybody have design notes or books they would recomend? Things like noise compensation and transformer selection/design.

For your sensor in your other post? If size is no constraint then a linear supply might be easiest. Switchers are small but have to be filtered heavily.

Is there some reason you don't want a qualified EE to do this?

There are some chips out there that you can use to make a low current/High Voltage DC-DC converter circuit.

However, if you are needing to do more than a basic one-chip DC-DC converter, I would suggest you look at the flow chart on page 1 of Linear Technology Application Note 73.

THEN - if you're really serious, read the remaining 63 pages of the application note.
