In pwm ( p ulse w idth m odulation), the overall switch time t is kept constant while the turn on time t on of the switch is varied. The lm2595 from on semiconductor is a monolithic integrated circuit that includes the main power switch and the control circuitry. The basic operation of the buck converter can be illustrated by looking at the two current paths represented by the state of the two switches: Output capacitor of 200 f is used to reduce voltage ripple in the output.
