19-1975; Rev 2; 7/03  
24V, 600mA Internal Switch, 100% Duty Cycle,  
Step-Down Converter  
General Description  
Features  
The MAX1776 high-efficiency step-down converter pro-  
o Fixed 5V or Adjustable Output  
o 4.5V to 24V Input Voltage Range  
o Up to 600mA Output Current  
o Internal 0.4P-Channel MOSFET  
o Efficiency Over 95%  
vides an adjustable output voltage from 1.25V to V from  
IN  
supply voltages as high as 24V. An internal current-limit-  
ed 0.4MOSFET delivers load currents up to 600mA.  
Operation to 100% duty cycle minimizes dropout volt-  
age (240mV at 600mA).  
The MAX1776 has a low 15µA quiescent current to  
improve light-load efficiency and conserve battery life.  
The device draws only 3µA while in shutdown.  
o 15µA Quiescent Supply Current  
o 3µA Shutdown Current  
High switching frequencies (up to 200kHz) allow the  
use of tiny surface-mount inductors and output capaci-  
tors. The MAX1776 is available in an 8-pin µMAX pack-  
age, which uses half the space of an 8-pin SO. For  
increased output drive capability, use the MAX1626/  
MAX1627 step-down controllers, which drive an exter-  
nal P-channel MOSFET to deliver up to 20W.  
o 100% Maximum Duty Cycle for Low Dropout  
o Current-Limited Architecture  
o Thermal Shutdown  
o Small 8-µMAX Package
