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

General Description 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-selec
