Description
The STEVAL-ISA096V1 is a switched mode
power supply (SMPS) demonstration board. This
non-isolated SMPS is designed in a buck-boost
topology and is capable of delivering up to 2 W of
output over a wide input voltage range.
This board also offers the user the possibility of
adapting the circuit to specific needs, thanks to an
available free PCB area.
The SMPS generates 12 V of nominal output
voltage.
The STEVAL-ISA096V1 demonstration board is
based on the VIPer06, a monolithic converter that
integrates an 800 V avalanche-rugged MOSFET
and PWM controller in one package, offering a
cost-effective and space-saving solution.
