GENERAL DESCRIPTION  
GAIN BLOCK/  
ERROR AMP  
I
LIM  
The ADP1173 is part of a family of step-up/step-down switching  
regulators that operates from an input supply voltage of as little as  
2 V to 12 V in step-up mode and to 30 V in step-down mode.  
SW1  
1.245V  
REFERENCE

COMPARATOR  
OSCILLATOR  
DRIVER  
SW2  
The ADP1173 consumes as little as 110 µA in standby mode,  
making it ideal for applications that need low quiescent current.  
An auxiliary gain amplifier can serve as a low battery detector,  
linear regulator (under voltage lockout) or error amplifier.  
R1  
ADP1173-3.3: R1 = 456k  
ADP1173-5: R1 = 250kΩ  
ADP1173-12: R1 = 87.4kΩ  
R2  
753kΩ  
GND  
SENSE  
The ADP1173 can deliver 80 mA at 5 V from a 3 V input in  
step-up configuration or 100 mA at 5 V from a 12 V input in  
step-down configuration. For input voltages of less than 2 V use  
the ADP1073.
