Hi, my name is Ray Pilukaitis. I'm a Field Applications Engineer for Intersil Corporation. I'm here to talk about some of our products, especially about the fact that we have such a wide variety of power products.

The first one I'd like to talk about here is the ISL8115, which is a controller for buck converters which operates over the range of 3 volts to 36 volts, which is a very good range for industrial type products. It uses external FETs, but has very powerful drivers, some 4-amp drivers in there, which allow the efficiency of your buck converter to be very high.

Moving down and parallel over from there, another industrial part here, the ISL85410, which is a 1-amp part which has the FETs integrated into the controller. Again, good from 3 volts to 36 volts, and also has a PFM mode where it runs at a lower frequency at light loads in order to conserve power, so excellent for battery type applications.

At lower voltage inputs, here, we have a variety of integrated FET type products. The one shown here is the ISL80019 and ISL8002, which is a 1.5- and 2-amp integrated FET product that works from a 2.5-volt up to 5-volt input range.

Moving up over here, we have an isolated power controller, the ISL6742. We have a wide variety of isolated controllers good for just about any type of isolated topology. This particular one is good for either half-bridge or full-bridge type applications. It has a unique average current type of control circuitry that will kick in when the device is in overload, so it actually allows your isolated converter, which normally has a tail-out or hiccup mode in over current mode, to act like, almost like a bench supply where the output voltage is controlled there in voltage mode, but if you go into overload, the current is a constant current.

And finally, we have here the ISL28022, which is a digital current sense part. So this part operates up to a 60-volt input. You can sense both the voltage and the current, and it will give you the results over an I2C BUS or a PM BUS for a digital readout of your voltage and current, and the current reading's extremely accurate. It has an equivalent offset of tens of micro-volts when it's doing its sensing across your shunt, so it allows you to use a very small shunt yet still get accurate results.
