MAX1797 General Description
The MAX1797 evaluation kit (EV kit) is a high-efficiency, step-up DC-DC converter for portable hand-held devices. Unlike typical boost circuits, the MAX1797 output is completely disconnected from the input in shutdown.
The EV kit accepts a positive input voltage between 0.7V and VOUT and converts it to a 3.3V output for currents up to 500mA. The EV kit provides ultralow quiescent current and high efficiency for maximum battery life.
The MAX1797 EV kit is a fully assembled and tested surface-mount printed circuit (PC) board. It can also be used to evaluate other output voltages in the 2V to 5.5V range. Additional pads on the board accommodate the external feedback resistors for setting different output voltages.
