SELF-OSCILLATING DRIVER WITH SOFT START CIRCUIT |
摘要 |
A method for providing a soft start operation for a transistor driver circuit, comprising providing a saw tooth waveform from an oscillator at a given frequency; comparing the saw tooth waveform to a reference value; and modifying the saw tooth waveform as a result of the comparison to produce pulses of increased length when the reference value is below a value of the saw tooth waveform.
