DESCRIPTION
The LM2773 is a switched capacitor step-down
regulator that produces a selectable 1.8V or 1.6V
output. It is capable of supplying loads up to 300mA.
The LM2773 operates with an input voltage from 2.5V
to 5.5V, accommodating 1-cell Li-Ion batteries and
chargers.
The LM2773 utilizes a regulated charge pump with
gains of 2/3x and 1x. It has very low ripple and noise
on both the input and output due to its pre-regulated
1.15MHz (typ.) switching frequency and spread
spectrum operation. When output currents are low,
the LM2773 automatically switches to a low-ripple PFM regulation mode to maintain high efficiency over
the entire load range.
The LM2773 is available in TI's 0.5mm pitch 9-bump
DSBGA.
