Given: V = L di/dt I(t) = I(t0) + 1/L × ∫ V(t) dt Rearrange: (L/V) × (I(t) - I(t0)) = dt Using the formula: PWM on-time = (L/V) × 2 × (IDESIRED - ISTART) For most applications, the input voltage can't ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

Editor’s Note: This is a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering ...

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...
