Current Control PWM Switching Power Supply

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

100V, 250mA, surface mount, high speed switching diode

MOS power IC full range

【Summary】
This paper introduces the basic principle of current-controlled PWM switching power supply (and compares it with voltage-controlled PWM switching power supply) (pointing out the advantages of current-controlled PWM switching power supply. Finally, a practical current-controlled PWM switching power supply is given for comparison, indicating current Control the advantages of PWM switching power supply, and finally give a practical current control PWM switching power supply circuit.
