I am searching for good components to design a switching ps DC/DC converter. Powered by 12V car battery. I need plus twelve, minus twelve, plus five, minus five volts to power onboard computer. I see that Maxim has some switching regulators, but don't know which to choose.
current requirements for -12 are .3 amps. +12 is about 2 amps. +5 about 6 amps. -5 2 amps.
Are there available schematics on the network or commercial units available?
