This application note presents a non isolated buck and buck-boost converter reference board based on the VIPer12AS monolithic device. The circuit can be used to produce a single, non isolated positive or negative voltage. It is dedicated for building an auxiliary power supply based on the VIPer12AS monolithic device with rather low output power required.
The document presents a circuit design for producing single, non-isolated positive or negative voltages using the VIPer12AS. It is intended for building auxiliary power supplies with low output power requirements. The reference board incorporates two variants: a buck converter providing +15V/100mA and a buck-boost converter providing negative voltage.
| Input Voltage Range | 90-264 VAC |
|---|---|
| Input Frequency | 50/60 Hz |
| Main Output Voltage (Variant 1) | +15V |
| Second Output Current (Variant 1b) | 60mA |
| Total Maximum Output Power | 1.6W |
It can be used to produce a single, non isolated positive or negative voltage for auxiliary power supplies.
The converter is dedicated for building an auxiliary power supply based on the VIPer12AS monolithic device.
The board includes a buck (step-down) converter with positive output and a buck-boost converter with negative output.
