LM2797 Overview
The LM2797/98 switched capacitor step-down DC/DC converters efficiently produce a 120mA regulated lowvoltage 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.
