    Power topology choices for power-hungry devices

    It is hard to choose a power topology for a wireless design when there are so many power-management integrated circuits (IC) out there. It may be hard to tell where to start, so I always start at the selection basics. The application of the design and onboard devices will determine the different voltage rails needed for operation. Consider a smart...

    How to deliver clean USB Type-C™ signals

    The rapid growth of USB Type-C enables a unified interface to deliver data, video, audio and power through a single connector. USB Type-C ™ not only supports the latest USB data rate of 10Gbps, it also enables up to 100W power delivery through the same cable carrying the data traffic simultaneously. Type-C has reversible plug orientation; it also...

    Help! My power supply unit is unstable – part 2

    In the first installment of this series, I stated that there are many reasons for switched-mode power supply (SMPS) instability, only one of which is that the control loop has insufficient gain or phase margin. In this installment, I will offer some tips about identifying and curing subharmonic oscillations in peak current mode (PCM)-controlled SMPS...

    How to use a boost bypass as the pre-regulator in a smartphone

    A typical power source for a portable device like a smartphone is a single lithium-ion battery. With the development of silicon anode material and maximizing the battery energy as much as possible, the minimum operating voltage in a smartphone application for example, is usually lower, for instance 2.7V. Some load configurations, such as Wi-Fi®...

    Understanding current sensing in HEV/EV batteries

    When I was six years old, I got a remote-control car as a present from my dad. With just a click of a button, I was able to control the car and it was running all around my home. One day, my brother and I suddenly got into a fight and broke the remote-control car into pieces. I was curious to look inside and see how it worked. I learned that remote...

    Do-it-yourself: Three ways to stabilize op amp capacitive loads

    Capacitive loads can cause stability problems in operational amplifier (op amp) circuits, resulting in large overshoots, ringing, long settling times – and in severe cases, sustained oscillations. These issues occur because the capacitive load ...

    Making a solar inverter more reliable than the sun

    Like most people on a wicked hot sunny day, all I can think about is how to beat the heat, which more often than not involves hiding in an air-conditioned room in my home. Later – on almost always a cooler day, with open windows – I’ll receive the electric bill and ask myself whether that temporary comfort was really worth it. The...
