EVALVIPER17L-7W: 12V @ 600mA, 90 ~ 265 VAC

The new VIPer17 device integrates in the same package two components: an advanced PWM controller built in BCD6 technology and an 800 V avalanche rugged vertical power MOSFET. The device is suitable for off line power converter operating both, with wide range input voltage (85 VAC - 270 VAC) up to 7 W or with single range input voltage (85 VAC - 132 VAC or 175 VAC – 265 VAC). With European range input voltage (175 VAC - 265 VAC) the device can handle up to 10 W of output power.

The proposed solution has the advantage of using few external components compared to a discrete solution, providing several switch mode power supply's protections and very low stand by consumption in no load condition.

VIPer17 device operates at fixed frequency that can be 115 kHz or 60 kHz according to the part number selected. Frequency jittering is implemented and it helps to meet the standards regarding electromagnetic disturbance. There are more protections present on the device like: overload, output short circuit, secondary winding short, hard transformer saturation protection and brown out protections, improve the reliability and safety of the design.

The present demonstration board is a standard one output isolated fly-back converter that uses all the protections above mentioned. If not necessary brown out protection and over-voltage protection could be not used reducing the number of external comp furthermore.
