![]() Finally, I had the tools that I needed to design an AC/DC charger that is just as good as or better than existing chargers based on size, efficiency and cost. Thankfully in 2012, TI introduced the UCC28700/UCC28710 family of flyback controllers. It only took a couple more failed attempts before I gave up. After the initial request, other similar business opportunities were beginning to pop up regularly. The power consumption (both at full load and no load) and the overall solution cost required a new type of controller. The size requirements turned out to be the least of my problems. I tried (unsuccessfully) to design the charger using one of our industry-standard, low-cost (very important!), fixed-frequency controllers. Just a few of years ago, I was asked to design a 5 watt smartphone charger for a large, aftermarket accessory manufacturer. In addition to a small form factor, chargers must be as inexpensive and efficient as possible. Remember those bulky “ wall warts” from just a decade ago? After all, nobody wants to plug their small smartphone into a giant power supply. ![]() However, power supply designers may be the only that noticed manufacturers of these products have also revolutionized the AC/DC adapter. It is obvious to most that the smart phone and tablet era has changed almost everyone’s life. ![]()
