The ADP3000 is a versatile step-up/step-down switching regulator that operates from an input supply voltage of 2 V to 12 V in step-up mode and up to 30 V in step-down mode.

The ADP3000 operates in Pulse Frequency Mode (PFM) and consumes only 500 µA, making it highly suitable for applications that require low quiescent current.

The ADP3000 can deliver an output current of 100 mA at 3 V from a 5 V input in step-down configuration and 180 mA at 3.3 V from a 2 V input in step-up configuration.

The auxiliary gain amplifier can be used as a low battery detector, linear regulator undervoltage lockout or error amplifier.

The ADP3000 operates at 400 kHz switching frequency. This allows the use of small external components (inductors and capacitors), making the device very suitable for space constrained designs.
