The MAX847 evaluation kit (EV kit) provides a platform for evaluating the features of the MAX847. The MAX847 converts a 1-cell, 0.8V to 1.8V 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 MAX847 offers numerous features for two-way paging and other low-power wireless designs. Consult the MAX847 data sheet for details. The MAX847 EV kit is a fully assembled and tested surface-mount circuit board.
The MAX769 is similar to the MAX847 except that it contains a buck/boost DC-DC converter (for 2-cell or 3-cell inputs) rather than a boost-only converter (for 1-cell inputs). To evaluate the MAX769, please order the MAX769EVKIT.
