com LM2770 High Efficie ncy Switched Capacitor Step-Down DC/DC Regulator with Sleep Mode December 200 4 LM2770 High Efficiency Switched Capa citor Step-Down DC/DC Regulator with Sl eep Mode General Description The LM2770 is a switched capacitor step-down regu lator that is ideal for powering low-vo ltage applications in portable systems.
The LM2770 can supply load currents up to 250mA and operates over an input vo ltage 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 LM2 770 can be dyn .
