Over-current sense
I am using a circuit shown below.
it is designed to sense 1.5 A whenever the load takes current >= 1.5 A. Rsen senses the related voltage and activates the transistor.
Here I use a Rsen = 0.46 R(0.7V/...

Closed loop control of PWM using current sensing method
This is the block diagram of the project i am working on. I have a DC voltage range of input as 8V to 16V.
The duty cycle at the PWM generation should change automatically from 10% to 90%. I require ...
