Overview
LM2772 Low-Ripple Switched Capacitor Step-Down Regulator December 2006 LM2772 Low-Ripple Switched Capacitor Step-Down Regulator General Description 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 automatica...
