Description
The STEVAL-ISA179V1 evaluation board
implements a wide mains range buck converter
(15 V / 0.15 A), developed for general purpose
applications.
The core of the application is the new VIPer0P
off-line high voltage converter of the VIPerPlus
family, featuring the Zero Power characteristic.
The device is a high-voltage converter that
intelligently integrates an 800 V rugged power
MOSFET with PWM current-mode control.
The evaluation board features a single layer
design, small size, minimal BOM, high efficiency
and low standby consumption.
