Charge-Pump Flying Capacitor Negative Connection (MAX15015/MAX15016 only)
Gate Drive Supply for the High-Side MOSFET Driver. Connect to REG and to the
anode of the bootstrap diode for MAX15014/MAX15017. Connect to REG for
MAX15015/MAX15016.
Charge-Pump Flying Capacitor Positive Connection (MAX15015/MAX15016 only).
Connect to the positive terminal of the external pump capacitor and to the anode of
the bootstrap diode.
Oscillator Synchronization Input. SYNC can be driven by an external clock to
synchronize the switching frequency. Connect SYNC to SGND when not used.
Error Amplifier Output. Connect COMP to the compensation feedback network.
Feedback Regulation Point. Connect to the center tap of a resistive divider from
converter output to SGND to set the output voltage. The FB voltage regulates to the
voltage present at SS (1.235V).
Soft-Start and Reference Output. Connect a capacitor from SS to SGND to set the
soft-start time. See the Applications Information section to calculate the value of the

Supply Input Connection. Connect to IN_LDO and an external voltage source from
4.5V to 40V. EN_SW and EN_SYS must be high and IN_SW must be above its UVLO
threshold for operation of the switching regulator.
Exposed Pad. The exposed pad must be electrically connected to SGND. For an
effective heatsinking, solder the exposed pad to a large copper plane.
