The recent advent of Analog Devices’ ADCMP60x family of comparators has filled a gap between the less-than-1-µsec-response comparators consuming 100 to 200 mW and those exhibiting approximately 1-µsec ...
Pulse-width modulation is a simple way to modulate, or change, a square wave. In its basic form, the duty cycle of the square wave changes according to some input. The duty cycle is the ratio of high ...
Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...
This file type includes high resolution graphics and schematics when applicable. Pulse-width modulation (PWM) is used in applications ranging from controlling valves or pumps to adjusting the ...
