Low-Voltage, Internal Switch,  
Step-Down Regulator  
MAX17083  
General Description  
Features  
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 25mΩ 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.  
o Fixed-Frequency, Current-Mode Controller  
o 2.4V to 5.5V Input Range  
o Internal 5A Step-Down Regulator  
o Internal BST Switch  
o Fault Protection: Undervoltage, Overvoltage,  
Thermal, Peak Current Limit  
o Enable Input and Power-Good Output  
o Voltage-Controlled Soft-Start  
o High-Impedance Shutdown  
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.  
o < 1µA (typ) Shutdown Current  
Applications  
Low-Power Architectures  
Ultra-Mobile PCs  
Netbook and Nettop PCs  
Portable Gaming  
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.  
Notebook and Subnotebook Computers  
PDAs and Mobile Communicators  
Ordering Information  
The MAX17083 is available in a 24-pin 4mm x 4mm x  
0.75mm TQFN package. The exposed backside pad  
improves thermal characteristics.
