STEVAL-ISA130V1

12 V 140 mA 30 kHz non-isolated buck topology regulator based on VIPer06XN
  • active Active

The STEVAL-ISA130V1 demonstration board implements a non-isolated buck topology regulator using the VIPer06, which supplies a 12 V output at up to 140 mA with an operating frequency of 30 kHz.

The output voltage of this power supply can be easily set by changing the value of one resistor.

The circuit can be powered by either 85 V to 265 V AC or 100 V to 375 V DC.
