INTRODUCTION
Pulse Width Modulation (PWM) modules, which produce basically digital waveforms, can be used in many applications
as a more efficient and lower power alternative to the traditional 8 bit Digital-to-Analog (D/A) converters using only two
inexpensive filter components. A wide variety of microcontroller applications that exist today are better served by utiliz-
ing a PWM generated analog output as opposed to an 8 bit D/A converter. One application where using a high resolution
PWM has value vs. a traditional 8 Bit DAC is in driving the 3-wire voltage controlled fan in a PC.
Audience
This document is written for a reader that is familiar with hardware design. The goal of this application note is to provide
information regarding how to use a PWM to drive 3-wire fans that provides system benefits and an enhanced customer
experience.
