12VDC to 37V DC converter by SG3524
Hello there!! How are you doing?
When my friend of I wants DC to DC converter circuit +37V GND -37V sizes use an automobile s have Voltage 12VDC. By he takes this circuit goes to Power Supply with , Mosfet Power Amplifier 100W RMS. A hand [...]

My cousin want buy IC dc converter,I like IC from www.linear.com because good ic,low cost and easy to used.
He are want 3V to 12V DC converter or switching power supply(switching-regulator).
Here is a DC converter Input 3V to output 12V,for electronics circuit.
The important part of the circuit is IC LT1073-12 again.
12V OUTPUT
35mA AT
VBATTERY = 2V
Detail more, [...]

This circuit will supply up to about 20ma at 12 volts. It uses capacitive reactance instead of resistance; and it doesn’t generate very much heat.The circuit draws about 30ma AC. Always use a fuse and/or a fusible resistor to be on the safe side. The values given are only a guide. There should be more [...]
