| Abstract: | Introduction was made to switching power supply design based on NCP1014. The working principle of switching power supply was analyzed, main circuit output voltage ripple diagram given out after the system was debugged. The switching power supply could pro- vide soft start, frequency jitter, short-circuit protection, skip cycle, maximum peak current setting and dynamic self-supply. The test results show that the output power and voltage ripple of switching power supply meet design requirements of the system and it is small in volume, high in transform effi ciency and low in cost etc. |
