An Analog-Friendly Approach Simplifies Digital Compensation
By Chris Young, Chief Technical Officer, Zilker Labs

Compensation of switching power supplies is an essential element of proper and robust power design. The recent introduction of digital pulse-width modulation (PWM) controllers has introduced the concept of using a digital proportional-integral-derivative (PID) filter for the voltage-loop compensation rather than a traditional Type III analog implementationmore>>
