Description
STEVAL-ISA023V2
This is an ideal solution for a 25 W switch mode
power supply (SMPS) dedicated to industrial or
white-goods applications. The board accepts a
wide range of input voltages (90 to 265 Vrms) and
delivers 2 negative output voltages. The switch-
mode power supply(SMPS) is based on the
VIPer53-E. The VIPer53-E combines an
enhanced current-mode PWM controller with a
high-voltage MDmesh™ Power MOSFET in the
same package. The main characteristics of the
evaluation board are its high efficiency and low
standby consumption. These, combined with the
minimal component count and global low cost
approach, makes it an ideal solution for powering
industrial or consumer equipment, while also
meeting worldwide consumption requirements.
