Figure 62. Speed of Response - Programming Down
Since
High performance bipolar power supply/amplifiers provide ultimate performance in high speed programming operation, with programming speed at least an order of magnitude faster than can be achieved with any standard power supply with reduced output capacitance.
More details on these versatile supplies are given in the Principles of Operation Section.
Supplies using SCR preregulator circuits cannot, in general, be expected to respond as rapidly as shown in Figures 61 and 62, since a change in output voltage must be accompanied by a change in rectifier voltage; the large value of the rectifier filter plus protection circuits within the SCR preregulator prevent the rectifier voltage from changing rapidly.
