HARDWARE SETUP

CURRENT/VOLTAGE SENSE OPTIONS

The DC2334A allows for evaluation of different current

sense/voltage measurement options.

High Side Current Sense

Figure 5 shows a typical application of LTC2947 where

the current from the external power supply is sensed on

the high side. Voltage is measured between IP and ground

(JP3 set to IP, JP4 set to GND) or by an external connec-

tion (JP3, JP4 set to default position EXT), for example,

between the supply or the load terminals.
