When potentiometer R1 is centered, operation is obvious and the duty cycle is 50%. However, as R1 is rotated in either direction the charge time and discharge times vary accordingly. The two sides of ...

A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

The duty cycle is the ratio of the turn-on time (TON) to the complete cycle length, the turn-off time (TOFF) plus on time, and defines a simple relationship between the input voltage and an output ...

The LM3495 PWM buck controller from National Semiconductor employs the company's emulated-current-mode architecture to generate output voltages with very low duty cycles at switching frequencies up to ...

High-performance motion control demands compact and economical servomotors. Fortunately, because most servo applications only intermittently demand maximum continuous-torque motor output, a smaller ...

Modern buck switching-regulator circuits need to provide lower and lower output voltages to power leading-edge digital logic ICs such as digital signal processors ...

If you need to regulate your power input down to a reasonable voltage for a project, you reach for a switching regulator, or failing that, an inefficient linear regulator. What if you need to boost ...

A lot of what real engineering is all about is designing to the limits of your materials, with a healthy margin for error. On the other hand, seat-of-the-pants ...
