LM2770 High Efficiency Switched Capacitor Step-Down DC/DC
Regulator with Sleep Mode
General Description
The LM2770 is a switched capacitor step-down
regulator that is ideal for powering low-voltage applications in portable systems.
The LM2770 can supply load currents up to 250mA and operates over an input voltage range of 2.
7V to 5.
5V.
This makes the LM2770 a great choice for systems powered by 1-cell Li-Ion batteries and chargers.
The output voltage of the LM2770 can be dynamically switched between two output levels with a logic input pin.
Output voltage pairs currently a...
