5-Pin SOT23-5 Package  
The ultra-small MAX828/MAX829 monolithic, CMOS  
charge-pump inverters accept input voltages ranging  
from +1.5V to +5.5V. The MAX828 operates at 12kHz,  
and the MAX829 operates at 35kHz. Their high efficiency  
(greater than 90% over most of the load-current range)  
and low operating current (60µA for the MAX828) make  
these devices ideal for both battery-powered and board-  
level voltage-conversion applications.

Applications include generating a -5V supply from a +5V  
logic supply to power analog circuitry. Both parts come  
in a 5-pin SOT23-5 package and can deliver 25mA with  
a voltage drop of 500mV.  
______________Ord e rin g In fo rm a t io n  
For applications requiring more power, the MAX860  
delivers up to 50mA with a voltage drop of 600mV, in a  
space-saving µMAX package.
