MAX1748EVKIT
Evaluation Kit for the MAX1748, MAX1779
|
Status
Active: In Production.
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.
