3V (MAX778L), 5V (MAX777L), and Adjustable (MAX779L) Output Voltage _______________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-selectable voltages of 3.
0V or 3.
3V, and the MAX779L output can be adjusted from...
