FUNCTION
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 the
IN supply, connect a resistive divider between IN, ON/ OFF , and SGND. Pull ON/ OFF to SGND to disable the
controller.
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 (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.
No Connection. Not internally connected.
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).
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.
Current-Sense Input. The current-sense signal is compared to a signal proportional to the error-amplifier output
voltage.
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.
7.4V Low-Dropout Regulator Output—Driver Power Source. Bypass V CC with 0.1μF and 1μF or higher ceramic
capacitors to PGND.
Exposed Pad (MAX15004A/MAX15005A only). Connect EP to the SGND plane to improve thermal performance.
Do not use the EP as an electrical connection.
