Description
The STEVAL-ISA136V1 evaluation board
implements a 5 V / 0.6 A isolated flyback 3 W
wide-range mains developed for general-purpose
applications.
The core of the application is the VIPER06HN, a
new off-line high voltage converter from the VIPer
plus family.
The IC combines a high-performance low-voltage
PWM controller chip and an 800 V, avalanche-
rugged power MOSFET in the same package.
The main characteristics of the board are its small
size, high efficiency and low standby
consumption. Extremely low consumption under
no-load conditions is ensured thanks to burst
mode operation, which reduces the average
switching frequency and minimizes all frequency-
related losses.
The VIPER06HN operates at fixed frequency (115
kHz). Frequency jittering is implemented, helping
it to meet electromagnetic disturbance standards.
The device is equipped with protection features,
such as delayed overload, open-loop failure and
hysteretic thermal protection, which improve the
reliability and safety of a design.
