the control switch and the pipe section time ratio, maintain a stable output voltage power supplies, switching power supply from the general pulse width modulationcontrol of IC and the MOSFER, with the development of power electronic technologyand innovation, making switching power supply technology is also in constant innovation. Then introduce some matters needing attention in design process of switching power supply, also introduced to when the switch power supply problems,how to quickly find out where the problem of switching power supply.
Switching power supply layout
Switching power supply is the use of modern electronic technology, the control switchturn-on and turn off time ratio, maintain a stable output voltage power supplies,switching power supply from the general pulse width modulation (PWM) control IC and MOSFET form.
