STEVAL-ISA058V1

5 W single output SMPS demonstration board

based on the VIPer17 off-line high voltage converter

Features

■ Input voltage range: 90 VAC to 265 VAC_RMS

■ Output voltage: 5 V

■ Maximum output current: 1 A

■ RoHS compliant

Description

The STEVAL-ISA058V1 demonstration board is a

5 W off-line power supply designed as an

evaluation platform for the VIPer17 offline high

voltage converter.

The VIPer17 features an 800 V rugged power

section, PWM control, two levels of overcurrent

protection, overvoltage and overload protection,

hysteretic thermal protection, soft-start and safe

auto-restart after fault condition removal. Burst

mode operation and the very low consumption of

the device help to meet standby energy saving

regulations. Advance frequency jittering reduces

EMI filter cost. A brown-out function protects the

switch mode power supply when the rectified

input voltage level is below the normal minimum

level specified for the system. A high voltage

startup circuit is embedded in the device.
