Voltage regulator Help - output higher than input

Voltage regulator Help

To voltage regulator experts,

I finished my linear regulator IC design. with varying input of 8-11V and producing a constant Vout=5.5V (this was successful).But I also need another constant Voltage=10V for the other circuits requiring 10V supply. But how can I do this if the input is varying from 9.7 down to 8V. I know I can design Boost regulator, but it is just too complicated and SPace consuming for my IC design.

Please enlighten me how to generate 10v output from varying 8-9.7V input.

Re: Voltage regulator Help

Hi

Basically you will need a boost circuit from lower voltage to higher one

all most all company who manufacture switching regulator have a boost type

the easy one to use is the one based on capacitor and can deliver up to 200mA

look at MP1517 from monolithic power to learn more

All the best
