Simple PWM using SG3525

Circuit diagram is one of a series of PWM. Circuit diagram is ideal for accurate control of DC motors. conversion of DC voltage pulses to the circuit IC is controlled by SG3525, such that the pulse duration is directly proportion to the value of DC voltage. Big advantage as the circuit is that almost no power loss in the control circuit. The output of the IC in order to move SG3525 DC motor must be strengthened, in the circuit diagram using the type JFET IRL520N. From the data sheet IC SG3525 has advantages such as protection against overload and short, PWM range can be adjusted 0-100%, PWM frequency of 100Hz-5KHZ adjusted. Operating voltage of 8 V ~ 35V, minimum current consumption is around 35mA. Maximum current can go to 6.5A. Efficiency better than 90% at full load. The following is a schematic drawing:
