STEVAL-ISA062V1: 5.5W, 5V @ 500mA, 12V @ 250mA

Summary

This demonstration board is based on the new VIPer17H device, that is a converter that offers in one package a PWM controller built in BCD6 technology and a 800 V avalanche rugged vertical power section.

The VIPer17H switches at 115 kHz and can deliver 6 W from wide range operation from 85 Vac to 305 Vac. It can also deliver 10 W when operating from European range of 175 Vac to 264 Vac.

This demonstration board has additional features asked by many customers:

Standby wattage as low as 50 mW at no load.
Frequency jittering is implemented to make EMI measurement meet today's standards.
Adjustable overload.
Output short-circuit protection for hard short such as transformer saturation or shorted diode.
Adjustable brown out and brown in feature.
Output over voltage protection.
