  • Resonant converters , especially the LLC series resonant converter (LLC-SRC) in Figure 1, have become popular over the last decade. Figure 1. Half-bridge LLC series resonant converter. When compared to traditional isolated PWM converters , LLC...
  • When the available input power is lower than the desired voltage in your system, you need a boost converter to boost (step-up) the input voltage. Examples include emergency call (eCall) systems, automotive start-stop systems, audio power amplifiers (PAs...
  • A key contributor to the cost of any electronic product is the number of layers used for the printed circuit board (PCB). An integrated circuit (IC) pin out arrangement optimized for PCB layout will help reduce end product cost. For example, the TPS23861...
  • I was recently hanging out with a college friend of mine that is a hardware designer for a satellite imaging start-up in the Bay Area, a.k.a. the "Center of the Universe" for new technologies like that of his company. There are only twelve employees...
  • The next time you are driving around your local town, look around and you’ll see more full-color LED signage and message boards in front of shops, restaurants and across office building walls than ever before. With the rapidly increasing production...
  • Many of my coworkers love to fish. They get up at four or five in the morning to go fishing, but not in the summer months because the high temperature drives fish away from shallow waters near shore. As the weather starts to cool down, many of them...
  • Starting September 11, TI’s leading power design gurus will be touring across the country for the 23 rd Power Supply Design Seminars ! The three-month series will provide rich technical and practical presentations combining new advanced power supply...
  • In order for any industry standard to reach wide adoption, two required characteristics are: interoperability and safety. In the case of Power over Ethernet (PoE), the technology’s reputation for both, heavily rests on how the source (Power Sourcing...
  • Part 1 of this series discussed the advantages of using an LDO in parallel with a DC/DC converter to optimize the no-load efficiency of the total power solution. In Part 2, I will discuss how this circuit was implemented with TI devices. The circuit...
  • Many power control and protection systems seek an integrated MOSFET along with the controlling IC in order to achieve two goals : (1) a smaller solution, (2) a lower cost solution. As you may know, such things are never as simple as we would wish....
