4.5V to 24V Input Voltage Range  
Preset 3.3V or 5V Output  
The MAX1836/MAX1837 hig h-e ffic ie nc y s te p -d own  
converters provide a preset 3.3V or 5V output voltage  
from supply voltages as high as 24V. Using external  
feedback resistors, the output voltage may be adjusted  
from 1.25V to V . An internal current-limited switching  
MOSFET d e live rs loa d c urre nts up to 125mA  
(MAX1836) or 250mA (MAX1837).  
Adjustable Output from 1.25V to V

Output Currents Up to 125mA (MAX1836) or  
250mA (MAX1837)  
The unique current-limited control scheme, operating  
with duty cycles up to 100%, minimizes the dropout  
voltage (120mV at 100mA). Additionally, this control  
scheme reduces supply current under light loads to  
12µA. High switching frequencies allow the use of tiny  
surface-mount inductors and output capacitors.  
Efficiency Over 90%  
12µA Quiescent Current  
3µA Shutdown Current  
100% Maximum Duty Cycle for Low Dropout  
Small 6-Pin SOT23 and TDFN Packages  
The MAX1836/MAX1837 step-down converters with  
inte rna l s witc hing MOSFETs a re a va ila b le in 6-p in  
SOT23 and 3mm x 3mm TDFN packages, making them  
ideal for low-cost, low-power, space-sensitive applica-  
tions. For increased output drive capability, use the  
MAX1776 step-down converter that uses an internal  
24V switch to deliver up to 500mA. For even higher cur-  
rents, use the MAX1626/ MAX1627 step-down con-  
trollers that drive an external P-channel MOSFET to  
deliver up to 20W.
