Multi-output switching power supply having an improved secondary output circuit |
摘要 |
A switching power supply wherein high speed switching and high output voltages are obtained by utilizing an auxiliary power supply and a synchronizing signal having a sawtooth shaped waveform, whereby delay time in a control signal to an FET switch is substantially reduced. The switching power supply comprises a secondary output circuit which is supplied with a square waveform voltage and utilizes an FET switch which controls the width of pulses chopped from the square waveform voltage and causes the output circuit to produce a direct current output voltage having a set value. The control signal to the FET switch is produced by a control circuit which is independently powered by the auxiliary power supply and supplied with the synchronizing signal.
