Description
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.
