Error Amplifier
The error amplifier in the HV911X is a true low-power differential
input operational amplifier intended for around-the-amplifier com-
pensation. It is of mixed CMOS-bipolar construction: A PMOS
input stage is used so the common-mode range includes ground
and the input impedance is very high. This is followed by bipolar
gain stages which provide high gain without the electrical noise of
all-MOS amplifiers. The amplifier is unity-gain stable.
Current Sense Comparators
The HV911X uses a true dual comparator system with indepen-
dent comparators for modulation and current limiting. This allows
the designer greater latitude in compensation design, as there are
no clamps (except ESD protection) on the compensation pin. Like
the error amplifier, the comparators are of low-noise BiCMOS
construction.
Remote Shutdown
The shutdown and reset pins of the 911X can be used to perform
either latching or non-latching shutdown of a converter as re-
quired. These pins have internal current source pull-ups so they
can be driven from open-drain logic. When not used they should
be left open, or connected to V
DD
.
Output Buffer
The output buffer of the HV911X is of standard CMOS construc-
tion (P-channel pull-up, N-channel pull-down). Thus the body-
drain diodes of the output stage can be used for spike clipping if
necessary, and external Schottky diode clamping of the output is
not required.
