Pin Description

PIN NAME

FUNCTION

1

IN

Input Power Supply. Bypass IN with a minimum 0.1µF ceramic capacitor to PGND.

ON/OFF Input. Connect ON/OFF to IN for always-on operation. To externally program the UVLO threshold of

2 ON/OFF 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.

Programmable Slope Compensation Capacitor Input. Connect a capacitor (CSLOPE) to SGND to set the amount

4 SLOPE of slope compensation.

Slope compensation = (2.5 x 10-9)/CSLOPE mV/µs with CSLOPE 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).

7

SGND Signal Ground. Connect SGND to SGND plane.

8

SYNC External-Clock Synchronization Input. Connect SYNC to SGND when not using an external clock.

9

SS

Soft-Start Capacitor Input. Connect a capacitor from SS to SGND to set the soft-start time interval.

10

FB

Internal Error-Amplifier Inverting Input. The noninverting input is internally connected to SS.

11 COMP 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

REG5 5V Low-Dropout Regulator Output. Bypass REG5 with a 1µF ceramic capacitor to SGND.

14 PGND Power Ground. Connect PGND to the power ground plane.

15

OUT Gate Driver Output. Connect OUT to the gate of the external n-channel MOSFET.

16

VCC

7.4V Low-Dropout Regulator Output—Driver Power Source. Bypass VCC with 0.1µF and 1µF or higher ceramic

capacitors to PGND. Do not connect external supply or bootstrap to VCC.

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.
