Maxim Integrated provides many LED (light-emitting diode) drivers, with PWM (pulse-width modulation) intensity control. This application note explains several methods for applying additional PWM-based intensity control to LED drivers. Several constant-current LED drivers, with or without built-in PWM...
PWM holds the frequency constant and varies the pulse width (tON) to adjust the output voltage. The average power delivered is proportional to the duty cycle, D, making this an efficient way to provide power to a load.As an example, for a desired output voltage of 15 V and an available...
Continuous PWM operation can handle a wide range of load currents, but the efficiency rapidly degrades at light loads because the power required by the regulator consumes a larger percentage of the total power delivered to the load. For portable applications, buck regulators incorporate additional ...
Modern low-power synchronous buck regulators use pulse-width modulation (PWM) as the primary operating mode. PWM holds the frequency constant and varies the pulse width (tON) to adjust the output voltage. The average power delivered is proportional to the duty cycle, D, making this an efficient...

to apply gain or not. The design and required components of VCA compressors allow them to be extremely versatile, transparent, precise, and physically smaller than older designs. While it’s easy to find examples of VCA compression on individual instruments, the most celebrated use for VCA ...
While most PWM systems have a frequency of 10 to 50 Hz, some can go up to 100 Hz. Single nozzle control is possible with PWM systems, allowing for a wide array of dosing rates without affecting the droplet size. For single nozzle VRA, farmers currently depend on proprietary so...
