My dream car
As ordinary people, we’re used to making tradeoffs between different product options. I would really like to drive a bright red, expensive sports car, but there’s no way I could save enough to buy one. But when I shop at my local grocery store, I almost always splurge for the Blue Bell ice cream instead of the store brand ice cream. For me, these types of tradeoffs, and countless others I make daily (or less often in the case of the sports car), relate to the value I receive for my purchase. The value of driving an exclusive car is not worth the price difference to a Toyota, but the value of fresher ice cream in full 1/2-gallon containers is certainly worth it.
As engineers, we also make tradeoffs between the various options presented to us in our design challenges. For my next smartphone or tablet design, do I use the same power supply I used on the last model, even though it initially took me a while to get working well, or do I use a newer supply that touts better performance and easier system integration? How much value does design reuse have versus optimizing the old design for the new application? Do I use what is tried and true or do I opt for cutting edge technology?
Now you can do both for your next power supply design! We have learned from our many years of power supply design and have created a new control topology that combines the advantages of the most familiar, traditional control topologies: voltage mode, current mode, and hysteretic. The result? DCS-Control: Direct Control with Seamless Transition into Power Save Mode. The high efficiency, low output ripple (even in power save mode), and seamless mode transitions will really take your next power supply up a notch. Imagine getting 90% efficiency at a 1-mA load current while still maintaining less than 1% output ripple. It’s now possible. The paper, "High-efficiency, low-ripple DCS-Control™ offers seamless PWM/power-save transitions," explains all the details of this value proposition.
What types of tradeoffs can the DCS-Control topology help you with in your next power supply design?
