A PWM-controlled regulator, this time using a logic gate IC, op-amp, and resistors and capacitors to buffer the PWM signal.

This pwm motor controller is using the fact that the small dc motor has the revolution speed depending on the power supply voltage. In this circuit the discharge time can be adjusted between 0.2ms and ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control ... or linear voltage regulators such as the LM317. I present here a PWM circuit that is ...

Learn how to create a DC motor speed control circuit using a PWM-based design for precise performance. This circuit enables voltage regulation, allowing motors to operate efficiently while ...

Complex circuits can be realized by mixing ... e.g., the GreenPAK acts as an output feedback controller and PWM. The voltage at GreenPAK 4 SLG46620V on pin 6 (Fig. 11) is the output feedback ...

Using PWM allows precise current control in the windings ... rise in the current through the winding in an RL circuit. When the applied voltage is removed from the circuit, the current slowly ...

High-voltage integrated circuits (HVICs) translate low-voltage control signals to levels that ... side in the form of a pulse-width modulated (PWM) signal. Another popular application for HVICs ...

This single-chip, highly integrated active-clamp current-mode PWM controller solution ... Protection features include OCP, short-circuit, thermal, under-voltage lockout (UVLO) and over-voltage ...

In this situation, the voltage across the current sense resistor drops to zero. The control circuit responds by increasing the PWM on-time to boost the output voltage higher in a failed attempt to ...

Analog circuits can also get very hot; the power dissipated is proportional to the voltage across the active elements multiplied ... What’s more, many microcontrollers and DSPs already include on-chip ...
