应用/用途

描述

The MAX756 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board. It can also be modified to fit the adjustable-output MAX757. 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 pin-selectable output voltage of 3.3V or 5V. The MAX757 is an adjustable version that accepts an input voltage down to 0.7V and generates a higher adjustable output voltage in the 2.7V to 5.5V range. Typical full-load efficiencies for the MAX756/MAX757 are greater than 87%.

A movable jumper selects either 3.3V or 5.0V output voltage, and additional pads on the bottom of the board are provided to place resistors for the LBI/LBO low-battery detector and MAX757 output adjustment.
