GENERAL DESCRIPTION  
GND  
SENSE  
The ADP1111 is part of a family of step-up/step-down switch-  
ing regulators that operates from an input voltage supply of 2 V  
to 12 V in step-up mode and up to 30 V in step-down mode.  
The ADP1111 can be programmed to operate in step-up/step-  
down or inverting applications with only 3 external components.  
Maximum switch current can be programmed with a single  
resistor, and an open collector gain block can be arranged in  
multiple configuration for low battery detection, as a post linear  
regulator, undervoltage lockout, or as an error amplifier.  
The fixed outputs are 3.3 V, 5 V and 12 V; and an adjustable  
version is also available. The ADP1111 can deliver 100 mA at  
5 V from a 3 V input in step-up mode, or it can deliver 200 mA  
at 5 V from a 12 V input in step-down mode.  
If input voltages are lower than 2 V, see the ADP1110.
