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.
