Features

Description

The STEVAL-ISA029V1 evaluation board is an

isolated triple-output flyback converter, suitable for

wide-range input voltage operation. The converter

is based on the smart power VIPer53-E, which

integrates, in the same package, an enhanced

current-mode PWM controller with a high-voltage

MDmesh™ Power MOSFET. The switching

frequency is set to 60 kHz by means of an

external RC network connected to a dedicated pin

on the IC. The closed loop regulation is performed

on the 12 V output using an optocoupler, which

drives the COMP pin of the VIPer. The 3.3 V

output is post regulated using a non-integrated

low drop linear voltage regulator to achieve the

required accuracy. The negative 24 V output is

achieved by means of a discrete linear voltage

regulator, made up of a Zener diode, a resistor

and a PNP transistor.
