Maximum Output Current
The MOSFET current limit is norminally 2.0A and
guaranteed 1.7A. This restricts the maximum output current
that the ISL97516 can drive. Table 1. shows the ISL97516
maximum output current, I
voltages.
and GND. The positive output of the power
supply should be connected to V
power supply voltage between 2.3V and 5V, and
current limit at 3A.
Close pin 2 and pin 3 of S1 to tie EN pin to VIN
to enable the part. Open pin 2 and pin 3 to pull
EN to ground with R3 to disable the part.
Connect power supply between headers of V
Connect E-load between headers of V
GND. The positive input of the E-load should be
connected to V
The load current should not exceed the
maximum output current the part can supply.
Close pin 1 and pin 4 of S1 to tie FSEL pin to
VIN to set 1.2MHz switching frequency. Open
pin 1 and pin 4 to pull FSEL to ground with R4 to
set 620kHz.
Make sure all the connections on the EVB are
correct, then turn on power supply and E-load.
The part starts to operate.
