The STEVAL-ISA183V1 evaluation board implements a 16 W triple output power supply designed in quasi-resonant flyback topology, specifically designed as an auxiliary PSU for air conditioning systems.
The core of the application is the VIPER35LD high voltage converter from the VIPerPlus product family which integrates an 800 V rugged power MOSFET with a quasi-resonant PWM current-mode control.
The power supply provides an isolated 12 V / 1 A output a two non-isolated outputs, 15 V / 200 mA and 5 V / 200 mA respectively.
Other key features include high conversion efficiency, the extremely low consumption at no-load and at minimum operative output conditions and excellent EMI performance using a low cost input filter.
All of these features are concentrated in a small PCB footprint and a minimal bill of materials.
