MAX757 Datasheet (Maxim) - 3.3V/5V/Adjustable-Output / Step-Up DC-DC Converters

MAX757, 3.3V/5V/Adjustable-Output / Step-Up DC-DC Converters

The MAX756/MAX757 are CMOS step-up DC-DC switching regulators for small, low input voltage or battery-powered systems.

The MAX756 accepts a positive input voltage down to 0.7V and converts it to a higher pinselectable output voltage of 3.3V or 5V.

The MAX757 is an adjustable version that accepts an
