NAME
FUNCTION
—
1
RTH
Current-Sense Threshold Setting Input. Connect a resistor from RTH to V
IN
to set the
fast comparator threshold. Bypass to V
IN
with 0.1
μ
F. Connect RTH to V
IN
to disable
both the fast comparator and current regulation at startup. Short RTH to GND for a
200mV threshold. See
Fast Comparator Threshold
section.

2
AUXVCC
Auxiliary Supply Input. Supply input for short-circuit switchover. To use this, connect a
1
μ
F capacitor from AUXVCC to GND; otherwise, leave floating. See
Auxiliary V
CC
section.

3
IN
Input Voltage. Connect to +2.7V to +13.2V supply; 15V absolute maximum voltage
rating.

SENSE
GATE
Current-Sense Resistor Voltage Input. R
SENSE
is connected from IN to SENSE.
Gate Drive Output. Connect to gate of external N-channel pass transistor.
—
6
CEXT
External Gate Capacitance Connection. Connect a capacitor from CEXT to GATE to
increase the gate charging time. This pin goes high impedance during a fast
comparator fault for fast discharge.
—
7
LLMON
Load Line Monitor. Connect to the source of the external N-channel MOSFET. The
external FET is turned on only when the load voltage is less than 100mV.

CTON
Startup Timer Input. Leave floating or connect the timing capacitor from CTON to GND.
See
Startup and Retry Timers
section.

CSPD
Slow Comparator Speed Setting. Leave floating or connect the timing capacitor from
CSPD to GND. See
Slow Comparator Response Time
section.
