5V to isolated 5V at 20mA converter by MAX635

When we need a constant voltage 5V at the current about 20mA, by there are power supply source voltage about 4V to 6V. In this circuit, We use the MAX635 IC number is the main equipment, that acts as Preset/Adjustable Output CMOS Inverting Switching Regulators. At pin A, a negative output dc-dc converter generates a […]
