LM2797/LM2798 120mA High Efficiency Step-Down Switched Capacitor Voltage Converter with Voltage Monitoring
General Description
The LM2797/98 switched capacitor step-down DC/DC converters efficiently produce a 120mA regulated low-voltage rail from a 2.
6V to 5.
5V input.
Fixed output voltage options of 1.
5V, 1.
8V, and 2.
0V are available.
The LM2797/98 uses multiple fractional gain configurations to maximize conversion efficiency over the entire input voltage and output current ranges.
Also contributing to high overall efficiency is the extremely low supply current of the LM279...
