Pin Description
PIN
1
NAME
IN
FUNCTION
Input Power Supply. Bypass IN with a minimum 0.1μF ceramic capacitor to PGND.
2
ON/
OFF
ON/
OFF
Input. Connect ON/
OFF
to IN for always-on operation. To externally program the UVLO threshold of the
IN supply, connect a resistive divider between IN, ON/
OFF
, and SGND. Pull ON/
OFF
to SGND to disable the
controller.
3
OVI
Overvoltage Comparator Input. Connect a resistive divider between the output of the power supply, OVI, and
SGND to set the output overvoltage threshold.
4
SLOPE
Programmable Slope Compensation Capacitor Input. Connect a capacitor (C
SLOPE
) to SGND to set the amount
of slope compensation.
Slope compensation = (2.5 x 10
-9
) / C
SLOPE
mV/μs with C
SLOPE
in farads.
5
N.C.
No Connection. Not internally connected.
6
RTCT
Oscillator-Timing Network Input. Connect a resistor from RTCT to REG5 and a capacitor from RTCT to SGND to
set the oscillator frequency (see the
Oscillator Frequency/External Synchronization
section.)

10
11
SGND
SYNC
SS
FB
COMP
Signal Ground. Connect SGND to SGND plane.
External-Clock Synchronization Input. Connect SYNC to SGND when not using an external clock.
Soft-Start Capacitor Input. Connect a capacitor from SS to SGND to set the soft-start time interval.
Internal Error-Amplifier Inverting Input. The noninverting input is internally connected to SS.
Error-Amplifier Output. Connect the frequency compensation network between FB and COMP.
12
CS
Current-Sense Input. The current-sense signal is compared to a signal proportional to the error-amplifier output
voltage.
13
14
15
REG5
PGND
OUT
5V Low-Dropout Regulator Output. Bypass REG5 with a 1μF ceramic capacitor to SGND.
Power Ground. Connect PGND to the power ground plane.
Gate Driver Output. Connect OUT to the gate of the external n-channel MOSFET.
16
V
CC
7.4V Low-Dropout Regulator Output—Driver Power Source. Bypass V
CC
with 0.1μF and 1μF or higher ceramic
capacitors to PGND.

EP
Exposed Pad (MAX15004A/MAX15005A only). Connect EP to the SGND plane to improve thermal performance.
Do not use the EP as an electrical connection.
