The MAX769 evaluation kit (EV kit) provides a platform for evaluating the features of the MAX769. The MAX769 converts a 2-cell or 3-cell, 1.5V to 5.5V battery voltage to four separate output voltages. The main output voltage at OUT is digitally controlled from 1.8V to 4.9V in 100mV steps by a 3-wire SPI™ serial interface. OUT provides up to 80mA. The other outputs (REG1, REG2, and REG3) are low-noise linear-regulator outputs. The MAX769 contains numerous other features for two-way paging and other low-power wireless designs. Consult the MAX769 data sheet for details. The MAX769 EV kit is a fully assembled and tested surface-mount circuit board.
The MAX847 is similar to the MAX769 except that it contains a boost DC-DC converter (for 1-cell inputs) rather than a buck-boost converter (for 2-cell or 3-cell inputs). To evaluate the MAX847, please order the MAX847EVKIT.
