Figure 7-4 shows a MAX622 connected to generate a regulated output voltage thati s 11 V greater than the input supply voltage. The primary use is to power high-side switching and control circuits．The output current is 25 mA. with a typical qulescentcurrent of 70 μA. Figure 7-5 shows quiescent Supply current test circuits. The MAX623 has internal charge－pump capacitors．The logic level PR (power ready) output indicates when the high-side voltage reaches the proper level．MAXIM NEWRELEASES DATA Book 1992 P． 4-31 4-37.
