FORCE 2
Output of Channel 2 control amplifier
to gate of external N-channel MOSFET.
Input from source of external MOSFET
to inverting input of Channel 2 control
amplifier, via output voltage-setting
feedback resistor network.
Digital Input. Active-low shutdown
control with 50
μ
A internal pull-up. The
output of Channel 2 control amplifier goes
to ground when
SHDN2
is taken low.
Device Ground Pin.

Input from source of external MOSFET to
inverting input of Channel 1 control ampli-
fier, via output voltage-setting feedback
resistor network.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body a
nd test equipment and can discharge without detection.
Although the ADM1051/ADM1051A features proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high-energy electrostatic discharges. Therefore,
proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.
WARNING!
