 Hi, my name is Marc Laudani and I'm marketing for industrial and power conversion with the ST Microelectronics and today I'm going to introduce you Viper 26K. Viper 26K is a device which is belonging to a wider family of products which is called Viper Plus and the aim of those products is to help designers to achieve small power supplies, aim to power anything which is below 15 watts. So it either can be a display driver into a wide good application, it can be a smart meter, it can be anything, a microcontroller in any kind of applications. But let's see what's unique about Viper 26K today. So the unique thing about this device which is here depicted in this implementation is that it's a compact device of a MOSFET together with a controller which is achieving a flyback configuration and the particularity of this device is that the MOSFET embedded in it, it's rated at 1,050 volts breakdown voltage. We have two kinds of possible implementation for this device. One is in a back converter as depicted in this board here, accepting the input voltage up to 600 volts AC or another possibility would be to have this device used in a flyback configuration accepting up to 440 volts input voltage, AC input voltage. What's particularly important about this device is that it is aimed to serve the 3 phase input voltage so especially adapted for 3 phase metering and what is using the device, the design with this device is that rather than stacking two MOSFETs with lower breakdown voltage you can just use this device and make much simpler the design, much more reliable, much more compact. So anytime you need a breakdown voltage above the traditional 700 or 800 volts then you can use this Viper 26K. Of course the family of the Viper is much broader than that and we have also many more products in this Viper Plus family with all MOSFET voltage rated 800 volts. We have many controllers. If we take a look at what is the product portfolio looking like you see here there is a matrix of products which are addressing different power from 4 to 15 watts and different type of controller and combining all those controllers with all those MOSFETs we get a matrix of products which is able to serve any kind of possible application. So if for your next auxiliary power supply design you need a Viper these are the products you need to look at from ST Microelectronics. For more information you can go to ST.com where you will find all the collaterals you will find the demo boards available and of course you can reach out to ST salespeople in order to get more support and assistance from ST.
