The LM2772 is a switched capacitor step-down regulator that produces a 1.2V output. It is
capable of supplying loads up to 150mA with 3% output voltage regulation over line, load, and
temperature. The LM2772 operates with an input voltage from 3.0V to 5.5V, accommodating 1-cell
Li-Ion batteries and chargers.
The LM2772 utilizes a highly efficient regulated multi-gain charge pump. Pre-regulated
1.1MHz fixed-frequency switching results in very low ripple and noise on both the input and the
output. When output currents are low, the part automatically switches to a low-ripple PFM
regulation mode to maintain high efficiency over the entire load range.
The LM2772 is available in TI’s WSON-10 Package (WSON-10).
