Linear regulators are simple voltage regulator circuits commonly used in electronics. This paper briefly discusses how linear regulators work, their advantages and disadvantages, variations on the linear regulator, and important datasheet parameters.

LEDs are used everywhere for status indicators, light sources, and more. This blog covers the basics of biasing low-current LEDs.

Current shunt monitors are a simple and easy way to measure current. This article introduces the ideas of current shunt sensing, some current shunt ICs, considerations when designing a current shunt monitor, and applications.

This paper discusses some loss mechanisms in DC-DC converters, and how careful component choices can optimize performance.

This article discusses the basic ideas of pulse-width modulation (PWM) and analog-to-digital conversion (ADC), and describes a circuit and firmware using these tools to create a constant power load with closed-loop feedback.

High-power LEDs produce more lumens per watt than previous lighting technology and are replacing incandescent and CFL light bulbs.
