MAX848 Datasheet (Maxim) - 1-Cell to 3-Cell / High-Power / Low-Noise / Step-Up DC-DC Converters

MAX848, 1-Cell to 3-Cell / High-Power / Low-Noise / Step-Up DC-DC Converters

The MAX848/MAX849 boost converters set a new standard of high efficiency and high integration for noisesensitive power-supply applications, such as portable phones and small systems with RF data links.

The heart of the these devices is a synchronous boost-topology regulator that generates a fixed 3.
