Power-Saving PWM Solenoid Controller

https://www.electronics-lab.com/power-saving-pwm-solenoid-controller/

The project described here is a power-saving pulse-width modulator (PWM) controller for solenoids with an internal supply regulator. The board is based on the DRV110 IC which is a PWM current controller which is specifically designed for solenoid and relay applications. The project regulates the current with a well-controlled waveform to reduce power dissipation on […]
