Designing with the ISL8541X

 Hi. My name is Paul Orfanu.  I’m an application engineer at Intersil and  I’m going to talk to you today the ISL8541X.  One of the common problems designers have with applications or systems require multiple input players or application different voltages is the need to qualify different IC’s specialized for different voltage.  This problem is solved by using ISL8541X, which covers a wide voltage range.  Covering from consumers to industrial some 3 volts to 36 volt input while having different output currents individually, all of them being ping to ping compatible.  This is the first one size fits all solution for regulators.

Let me show you how well the output stays in regulation. (DEMO) This is the ISL8841X.  This is input voltage and this is monitoring the output voltage, and this is monitoring the output voltage.  This is the output guide that we’re monitoring electronically.  

(DEMO) I’m going to increase the voltage and monitor the output.  I’m going to increase the voltage from zero all the way to slowly all the way to number thirty six. See we are all in regulation.  I’m going to apply five hundred amps.  While at thirty six volts while monitoring the output I’m going to change the load to zero and run a load regulation test, then back up to five hundred.  With five hundred I’m going to sweep the line back to zero voltage while monitoring the output voltage.  As you can see the output stays in the output stays in very tight regulation for the entire input voltage range.  

The next video will show how easy it is to design an application using ISL85415.  To order your own demo board goes to
