    A bite-size gate drive: replacing BJTs with an integrated solution

    Sushi is wonderful. It packs a fresh, satisfying flavor into a small package that melds the subtleties of just a few ingredients to make something special. It reminds me of the ideal power supply: a small, efficient collection of stages that produces the power to drive your amazing product. In this analogy, the power factor correction (PFC) stage...

    Cycle scavenging on C2000™ MCUs, part 5: TMU and CLA

    In parts 1 through 4 of this series , I’ve described several differentiating features built around the analog-to-digital converter (ADC) modules that enable C2000™ microcontrollers (MCUs) to scavenge cycles at the sensing stage. In this installment, I’ll turn my attention to the processing stage and focus on some of the built-in features...

    25 functions for 25 cents: pulse width modulation

    Are the light-emitting diodes (LEDs) in your design shining too brightly? Do you want to control the amount of voltage fed to a load, or vary the rotation speed or distance of a motor? Ever require an analog output from a digital device? You can acc...

    Merging wired and wireless connectivity to build an intelligent gateway to the cloud

    Analyst firm IHS Markit predicts that by 2025, the Internet of Things (IoT) will comprise as many as 75 billion connected things. To reach this large number, manufacturers will need to merge their legacy systems (with decades-old infrastructures comprising mostly wired protocols) with always-evolving wireless connectivity standards and technologies...

    Make a boost converter quieter

    In order to minimize the power loss of a boost converter under light or no load conditions, designers usually use the Pulse Frequency Modulation (PFM) to lower the switching frequency and hence the associated switching losses. In PFM more and more switching pulses are skipped as the load is getting lower, as shown in Figure 1. Obviously these scattered...

    How to design a simple constant current/constant voltage buck converter

    Introduction A DC-to-DC converter is typically implemented as a constant voltage (CV) regulator. The control loop will adjust the duty cycle in order to maintain a constant output voltage regardless of changes to the input voltage and load current. A constant current (CC) converter regulates current the same way: the control loop adjusts the duty...

    How to use load switches and eFuses in your set-top box design

    Sitting in front of a TV is easy. Changing the channel is easy. Recording four shows at once while watching one show on your TV and streaming another show to your tablet is excessive – but also easy! It’s all thanks to the power of set-top boxes (STBs), such as the one shown in Figure 1. Figure 1: A typical STB STBs take in a cable...

    Voltage and current sensing in HEV/EV applications

    This post was co-authored by Ryan Small . The rapid increase of semiconductor content in automotive systems has prompted a need to manage key voltages and currents in each subsystem. Supervising supply voltages, load currents or other important system functions can help indicate fault conditions, prevent catastrophic failures and protect end users...
