Hi all engineers
Please help for schematic 12V to 24V dc-dc converter that capable for 5 Ampere.
I will use for VSAT that using 24V DC, but the supply from battery 12v/100AH.

Thank's

 

5 Amps is a little high for most boost ckts I've seen , but maybe this would work: http://www.aaroncake.net/circuits/inverter.asp On transformer core wind 24 turns- tap & 24 more turns for primary & abuot 52 turns for secondary. Use a bridge rectifier & capacitor to get DC. No guarantees.

 

Hello,

if you don't like to make a transformer, I have 3 circuts with ICs. This circuits are designed by WEBENCH of National Semiconductors and Texas Instruments.
