Description

The MAX1748 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a boost switching regulator and two charge-pump voltage- regulator circuits. The boost switching circuit is configured for a +10V output that provides up to 200mA of current from a supply voltage of +2.7V to +5.5V.

The positive charge-pump circuit is configured for a +15V output that provides > 20mA of current. The negative charge-pump circuit is configured for a -5V output and provides > 20mA of current. Power for either or both charge-pump inputs can be provided from the +2.7VDC to +5.5VDC source or from the boost switching- regulator output.

The MAX1748 EV kit demonstrates low-quiescent current and high efficiency (over 86%) for maximum battery life. Operation at 1MHz allows the use of tiny surface- mount components. The MAX1748 TSSOP package (1.1mm max) with low-profile external components allows this circuit to be less than 1.2mm high. The MAX1748 EV kit can also be used to evaluate the MAX1779 IC.
