The MAX15014–MAX15017 provide undervoltage lock-
out (UVLO). The UVLO monitors the input voltage
(V IN_LDO ) and is fixed at 4.1V (MAX15015/MAX15016)
or 7V (MAX15014/MAX15017).
Internal Linear Regulator (REG)
REG is the output terminal of a 5V (MAX15015/
MAX15016), or 8V (MAX15014/MAX15017) LDO which
is powered from IN_SW and provides power to the IC.
Connect REG externally to DVREG to provide power for
the high-side MOSFET gate driver. Bypass REG to
SGND with a ceramic capacitor (C REG ) of at least 1μF.
Place the capacitor physically close to the MAX15014–
MAX15017 to provide good bypassing. During normal
operation, REG is intended for powering up only the
internal circuitry and should not be used to supply
power to external loads.
