Features
Description
This reference design is an auxiliary power supply
based on the VIPer12AS monolithic device and
can be used to produce multiple non isolated
positive or negative voltage outputs.
This solution is based on an offline discontinuous
current mode fly-back converter without isolation
between input and output. The fly-back topology
allows the exploitation of the VIPer12AS current
capability when compared with the buck converter
based power supply. To ensure power supply low
cost, the isolation between input and output is not
provided. This greatly simplifies the transformer
design and production. The VIPer12AS
incorporates the PWM controller with a 60kHz
internal oscillator and the vertical Power MOSFET
switch in a SO-8 package. The presented power
supply has four variants. All the variants have
been incorporated in the presented reference
board through different assembly options.
