DESCRIPTION
resistors. See Table 5 for jumper selection of input volt-
age ranges.
The MAX1748 EV kit can be reconfigured to evaluate
the MAX1779EUE. Replace the components listed in
Table 6. The boost switching regulator output (V1)
+5.1V and provides up to 50mA to 100mA of current,
depending on the inductor value and output capaci-
tance chosen. The positive and negative charge-pump
outputs provide +9V (VP) and -4V (VN) at their outputs.
Table 6 below lists the components that must be
replaced to evaluate a MAX1779.
