描述

The MAX1672 evaluation kit (EV kit) integrates a step-up switching converter with a linear-regulator output to provide step-up/down voltage conversion. It accepts a 1.8V to 11V input and converts it to a 3.3V or 5V output for currents up to 300mA. The EV kit is optimized for battery applications where the input varies above and below the regulated output voltage. It provides ultra-low quiescent current and high efficiency for maximum battery life. Another benefit of the low-dropout linear post-regulator is that it reduces high-frequency ripple.

The MAX1672 EV kit is a fully assembled and tested surface-mount circuit board. With minimal modification, it can also be used to evaluate other output voltages. Additional pads on the board accommodate external feedback resistors for setting different output voltages.
