Description
The MAX1642 evaluation kit (EV kit) is a step-up switching regulator for one-cell, battery-powered systems. It accepts a positive input between 0.9V and 1.65V and converts it to a 3.3V preset output for currents up to 20mA. The MAX1642 EV kit provides ultra-low quiescent current and high efficiency for maximum battery life. Operation up to 50kHz allows the use of a tiny surface-mount inductor while minimizing interference with sensitive intermediate frequencies in pagers and other RF applications.
This EV kit is a fully assembled and tested surface-mount circuit board. Additional pads on the bottom of the board accommodate the external feedback resistors for setting different output voltages. It can also be used to evaluate the MAX1643.
