Hi,

i want to generate 40 V DC and 350mA current from input ac (230v). how can i generate this? any direct ic available ?

Some googling for 'switched mode power supply' (SMPS) should give plenty of hits to guide you.

step voltage down using transformer, add bridge rectifier and filtering capacitor
transformer can be 30VAC out, 15W. rectifier can be four 1N4002 diodes, capacitor can be 1000uF/63V

THANKS BUDDY..

by some googling i got 1 good circuit.

1st i will convert ac to dc and then i will get appropriate voltage via dc to dc converter ic.
