Ideas, Tips & Solutions for Design Engineers
Welcome to an updated version of our “Design Ready” newsletter.
Our goal is to help you quickly and cost-effectively build efficient power management solutions. You’ll read about new technologies, how to solve design problems, and discover how others are handling emerging application issues.
Reducing the number of components in a design by replacing a discrete implementation with an integrated module usually goes hand-in-hand with several highly attractive design attributes. While the out-of-pocket cost of a module may exceed the total cost of a comparable discrete approach, designers typically come away with a simpler design in a highly scalable architecture, improved thermal performance, increased reliability and faster time-to-market. Moreover, the use of modules also promises to simplify the procurement process by allowing designers to source from fewer vendors. In many cases these multiple benefits translate into a lower total system cost.

In most power supply designs engineers face a few relatively universal challenges. Typically they must carefully manage thermal conditions, ensure their power supply runs within its operating range, and minimize volume, space and cost requirements while maximizing electrical efficiency.

Thinking of designing battery chargers for next-generation smart phones, feature phones or tablets? Keep an eye out for front end PWM controllers that offer extremely low standby power consumption, particularly if you want to meet Energy Star's 5-star level (<30 mW). And if you are planning to support the latest higher performance charging specifications like Qualcomm's Quick Charge 2.0, make sure the device can switch between 5V, 9V and 12V operation. Finally to keep device footprint small and cost low, look for a controller that eliminates as many external components as possible.
