manufacturer: description:the por function initiates the soft-start sequence. an internal 10µa current source charges an external capacitor (css) on the ss pin to 4v. soft-start clamps the error amplifier output (comp pin) to the ss pin voltage. figure 3 shows the soft- start interval. at t1 in figure 3, the ss and comp voltages reach the valley of the oscillators triangle wave. the oscillators triangular waveform is compared to the ramping error amplifier voltage. this generates phase pulses of increasing width that charge the output capacitor(s). this interval of increasing pulse width continues to t2, at which point the output is in regulation and the clamp on the comp pin is released. this method provides a rapid and controlled output voltage rise. |
