Description
The STEVAL-ISA180V1 evaluation board
implements a wide mains range flyback isolated
converter (12 V - 0.6 A), developed for general
purpose applications.
This high-voltage converter intelligently integrates
an 800 V rugged power MOSFET with PWM
current-mode control. The core of the application
is the new VIPer0P off-line high voltage converter
from VIPerPlus family with zero power features.
The evaluation board features a small size and
minimal BOM, high efficiency, low standby
consumption and high reliability due to these
protections: pulse skip mode to avoid flux-
runaway, delayed overload protection (OLP),
max duty cycle counter, VCC clamp and thermal
shutdown.
