MAX777L Datasheet (Maxim) - Low-Voltage Input / 3V/3.3V/5V/ Adjustable Output / Step-Up DC-DC Converters

MAX777L, Low-Voltage Input / 3V/3.3V/5V/ Adjustable Output / Step-Up DC-DC Converters

The MAX777L/MAX778L/MAX779L are pulse-skipping DC-DC converters that step up from low-voltage inputs (1V guaranteed).

They require only three external components *an inductor (typically 22µH) and two capacitors.

The MAX777L delivers a 5V output, the MAX778L generates pin-selectable voltages o
