19-1798; Rev 0; 12/00  
Low Supply Current, Step-Up DC-DC Converters  
with True-Shutdown  
General Description  
Features  
The MAX1795/MAX1796/MAX1797 are high efficiency  
step-up DC-DC converters intended for small portable  
hand-held devices. These devices feature Maxim’s  
True-Shutdown™ circuitry, which fully disconnects the  
output from the input in shutdown, improves efficiency,  
and eliminates costly external components. All three  
devices also feature Maxim’s proprietary LX-damping  
circuitry for reduced EMI in noise-sensitive applica-  
tions. For additional in-system flexibility, a battery moni-  
toring comparator (LBI/LBO) remains active even when  
the DC-DC converter is in shutdown.  
o >95% Efficiency  
o True-Shutdown Circuitry  
Output Disconnects from Input in Shutdown  
No External Schottky Diode Needed  
o 25µA Quiescent Supply Current  
o Low-Noise Antiringing Feature  
o LBI/LBO Comparator Enabled in Shutdown  
o 2µA Shutdown Current  
The input voltage range is +0.7V to V  
, where V

o 8-Pin µMAX Package  
can be set from +2V to +5.5V. Startup is guaranteed  
from +0.85V. The MAX1795/MAX1796/MAX1797 have a  
preset, pin-selectable 5V or 3.3V output. The output  
can also be adjusted to other voltages, using two exter-  
nal resistors. The three devices differ only in their cur-  
rent limits, allowing optimization of external components  
for different loads: The MAX1795, MAX1796, and  
MAX1797 have current limits of 0.25A, 0.5A, and 1A,  
respectively. All devices are packaged in a compact 8-  
pin µMAX package that is only 1.09mm tall and half the  
size of an 8-pin SO.
