Manufacturer:IXYS Description:Figure 6 illustrates the timing of this operation. The small initial delay (about 40 milliseconds) is the time interval during which VADJ > VREF. Since VIN is usually fairly consistent in value R3 may be chosen to minimize this delay. Note that if R3 is calculated based on the minimum foreseen VIN (as described below), then higher values of VIN will produce additional delay before the turn-on ramp begins. Conversely, if VIN (max) is used for the calculation of R3, then lower values of VIN will not produce the desired turn-on characteristic; instead, there will be a small initial step-function prior to the desired turn-on ramp. Recovery from a momentarily shorted output is not addressed by this circuit, but interrupted input voltage is handled properly. Notice that the build-up of regulator output voltage differs from the waveforms of Fig- ures 2 and 4 in that it is more ramp-like . This is because only an initial portion of the RC charge waveform is used; i.e., while VCONTROL > VREF+0.6V. The actual time constant used for Figure 5 is 0.33 second, so 3 is one second. As shown by Figure 6, this provides about 600 milliseconds of ramp time, |
