Description
The STEVAL-ISA137V1 demonstration board
implements an isolated flyback (5 V / 0.6 A) 3 W
wide-range mains developed for general-purpose
applications.
The core of the application is the VIPer06HS, a
new offline 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 demonstration
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 VIPer06HS operates at fixed frequency, 115
kHz. Frequency jittering is implemented, enabling
it to meet the standards for electromagnetic
disturbance. Protection features on the device,
such as delayed overload, open loop failure and
hysteretic thermal protection, improve the
reliability and safety of the design.
