555 timer converted into pulse-width modulator -  02/15/07  EDN Design Idea   his Design Idea   describes a new approach to producing a variable-duty-cycle waveform from a 555-based free-running oscillator. The circuit's wide modulation range, highly linear control over a wide range of duty-cycle values, and excellent linearity make it ideal for PWM (pulse-width-modulation) -based control applications. Figure 1 shows the basic circuit, which works as follows: When IC1's output goes high, switch S1 closes, and IC1's internal discharge, switch S2, opens. Capacitor C1 charges through R1 and R2. When IC1's output goes low, S1 opens, and S2 closes, discharging C1 through R2 and R3. . . .  [by Jordan Dimitrov, Tradeport Electronics, Vaughan, ON, Canada]
