ADP1110
GENERAL DESCRIPTION
The ADP1110 is part of a family of step-up/step-down switch-
ing regulators that operate from an input voltage supply of as
little as 1.0 V. This very low input voltage allows the ADP1110
to be used in applications that use a single cell as the primary
power source.
The ADP1110 can be configured to operate in either step-up or
step-down mode, but for input voltages greater than 3 V, the
ADP1111 would be a more effective solution.
An auxiliary gain amplifier can serve as a low battery detector as
well as a linear regulator.
The quiescent current of 300
A makes the ADP1110 useful in
remote or battery powered applications.
The 70 kHz frequency operation also allows for the use of sur-
face mount external capacitors and inductors.
Battery protection circuitry limits the effect of reverse current to
safe levels at reverse voltages up to 1.6 V.
