The ADP1111ARZ-5 is part of a family of step-up/step-down switchingregulators that operates from an input voltage supply of 2 Vto 12 V in step-up mode and up to 30 V in step-down mode.The ADP1111ARZ-5 can be programmed to operate in step-up/stepdownor inverting applications with only 3 external components.
The fixed outputs are 3.3 V, 5 V and 12 V; and an adjustableversion is also available. The ADP1111ARZ-5 can deliver 100 mA at5 V from a 3 V input in step-up mode, or it can deliver 200 mAat 5 V from a 12 V input in step-down mode.
Maximum switch current can be programmed with a singleresistor, and an open collector gain block can be arranged inmultiple configuration for low battery detection, as a post linearregulator, undervoltage lockout, or as an error amplifier.
