STEVAL-ISA062V1

The STEVAL-ISA062V1 is a demonstration board based on the VIPer17H device, a converter that offers in one package a PWM controller built in BCD6 technology and a 800V avalanche rugged vertical power section. The VIPer17H switches at 115KHz and can deliver 6W from wide range operation from 85Vac to 305Vac. Standby wattage as low as 50mW 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. The same PCB board has been designed in such a way that can be populated for either the double or even single output. The only difference between them is the extra output parts, the transformer, and the voltage divider for the feedback loop.
