PWM profile:

It is primarily by changing the duty cycle of the output square wave, such that the average load on the on-time changes from 0-100%, to achieve the purpose of adjusting the brightness of the load / speed. The use of pulse width modulation (PWM) mode to achieve the benefits of dimming / governor's energy supply can be fully utilized, the high efficiency of the circuit. For example: When the output is 50% of the square wave, pulse-width modulation (PWM) power supply circuit are consumed energy is 50%, that is, almost all the energy is converted to a load power output. The use of a common resistance when the buck converter, the power to make the load to get the maximum output power of 50% of the power supply must provide more than 71% of the output power, of which 21% is consumed in the resistor voltage drop and heat dissipation.
