This document introduces the STEVAL-ISA005V1 1.8W buck topology power supply evaluation board with VIPer12AS, which features an input voltage range of 85 to 264Vac @ 50/60Hz, a 15V, 100mA output voltage and power, and a second output of 5V / 60 or 20mA.
The STEVAL-ISA005V1 is an auxiliary power supply evaluation board designed as a switch-mode general-purpose power supply. It utilizes the VIPer12AS monolithic device, which integrates a PWM controller and vertical Power MOSFET in a SO-8 package.
The board provides a primary output of 15V at 100mA (1.6W pick) via a buck topology. Additionally, it offers an optional second output through a linear regulator (L78LO5CD or L78MOSCDT), providing either 5V/60mA or 5V/20mA depending on the selected component.
