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
The LM2773 is available in TI's 0.5mm pitch 9-bump DSBGA.
