Low-Voltage, Internal Switch,
Step-Down Regulator
General Description
The MAX17083 is a fixed-frequency, current-mode,
step-down regulator optimized for low-voltage, low-
power applications. This regulator features dual internal
n-channel MOSFET power switches for high efficiency
and reduced component count. External Schottky
diodes are not required. An integrated boost switch
eliminates the need for an external boost diode. The
internal 25m Ω low-side power MOSFET easily supports
continuous load currents up to 5A. The MAX17083 pro-
duces an adjustable 0.75V to 2.7V output voltage from
the system’s 3.3V or 5V input supply.
This step-down regulator uses a peak current-mode
control scheme to eliminate the additional external
compensation required by voltage-mode architectures,
providing an easy-to-implement architecture without
sacrificing fast transient response. The MAX17083 pro-
vides peak current-limit protection and operates in
light-load pulse-skipping mode to maintain high effi-
ciency under light-load conditions.
Independent enable input and open-drain power-good
output allow flexible system power sequencing. The volt-
age soft-start gradually ramps up the output voltage
within a predictable time period, effectively limiting the
inrush current. The MAX17083 features output undervolt-
age, output overvoltage, and thermal-fault protection.
The MAX17083 is available in a 24-pin 4mm x 4mm x
