The input voltage ranges from 2.6V to a maximum of 50V. Operation with large input to output differential voltages is limited by the maximum power dissipation available from package and environment. Figure 1: Kit Content www.ams.com Revision 1.0 / 30.10.2013 page 3/11 AS1370-AN01-Evaluation Board Description 2 Hardware Description The Evaluation Board has to be supplied via the pins VIN and GND in the range of 2.6V up to 50V. The jumper “SHDN” section C in the picture below has put to “on” (downwards) in order to enable the chip. On the AS1370 Evaluation Board the output voltage is factory-set to 3.3V.
