    When and how to supply an external bias for buck controllers – part 3

    In part 1 of this series, I discussed the need for an external bias and under what conditions you need to consider one. In part 2 , I discussed whether you can apply an external bias to any controller. In this third and final installment, I will go over a circuit that you can use to generate an external bias for any controller. This may prove useful...

    Integrating next-generation linear resonance actuator systems

    In my last blog post , I introduced new actuator technology and briefly talked about the need for higher-voltage drivers. In this post, I’ll go into more detail about these high-voltage drivers and four system considerations – waveform synthesis, waveform effects, delay time and actuator placement – that you should keep in mind while...

    Cycle scavenging on C2000™ MCUs, part 7: PWM valley switching

    In the sixth (and most recent ) installment of this series , I started the discussion about actuation by highlighting the importance of the delayed trip feature in implementing deadband delays in peak current-mode control with zero software overhead. In this installment, I will explore pulse-width modulation (PWM) valley switching, which is a soft switching...

    Power Tips: How to protect a USB Type-C™ controller from legacy adapters

    In the last couple of years, more and more portal devices such as notebooks and smartphones have employed USB Type-C™ as the interface port. The USB Type-C connector is a totally new USB connector. It has a set of great profile, power rating and data transmission speed improvements. But the most important change about this charging protocol is...

    Hybrid electric vehicles and electric vehicles need different isolated DC/DCs to win

    An hybrid electric vehicle and electric vehicle (HEV/EV) has various subsystems and critical components working together. Isolated DC/DC converters work similar to how players practice a play from the team playbook, each with their own individual assignments for the greater good of the team. If you’re a football fan, you probably recognize...

    Power a RS-485 transceiver with a high efficiency flyback converter

    RS-485 is a standard defining the electrical characteristics of drivers and receivers for use in serial communication systems. It defines not only a single device-to-device interface, but also a communications bus that can form simple networks of multiple devices. RS-485 runs on twisted-pair cable, and the voltage differential of the two lines defines...

    When and how to supply an external bias for buck controllers – part 2

    In part 1 of this series, I discussed the need for external bias and under what conditions you need to consider it. In this installment, I will look at whether you can apply external bias to any controller. As a rule of thumb, you cannot apply external bias to controllers that have a current limit for the control field-effect transistor (FET) (also...

    When and how to supply an external bias for buck controllers – part 1

    In multi-rail systems system designers often have to make the choice of where to tap into for the input rail for the buck controllers. Often it is from 12V or 24V rails, however in some cases it’s from 5V or 3.3V rails. I will be discussing the need to supplying external bias and its benefits in the first part of this 3 part series. Well, it...

    Don’t limit your audio: how to achieve loud sound from a small speaker

    One common challenge audio design engineers run into today is getting loud audio from a small speaker in systems with a single cell battery. The best solution is to give the amplifier more power. In portable electronic devices, implementing a Class-D audio amplifier with a boost will deliver that extra power. Unfortunately, the power needed to achieve...

    Ultrasonic sensing, part 1: an effective and improved approach to gas-flow metering

    Ultrasonic sensing is an emerging technology in the industrial and residential gas-flow metering space . In fact, ultrasound is a better alternative to mechanical flow metering because it enables the measurement of much lower flow rates while consuming very little power. Because there aren’t any moving parts in an ultrasonic flow meter, these...
