| ISL97516 Evaluation Board Application Manual Application Note March, 2008 ANXXXX The ISL97516 EVB is an evaluation kit for evaluating the ISL97516, a step-up voltage regulator that operates with high frequency and high efficiency. This evaluation kit is designed to deliever over 90% efficiency. The ISL97516 EVB kit provides a dip switch that allows users to select either 620kHz or 1.2MHz switching frequency.

Application Note XXXX Quick Setup Guide Step 1 Step 2 Step 3 Step 4 Step 5: Connect power supply between headers of VIN and GND. The positive output of the power supply should be connected to VIN header. Set power supply voltage between 2.3V and 5V, and current limit at 3A. Connect E-load between headers of VOUT and GND. The positive input of the E-load should be connected to VOUT header. Set E-load current. 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. 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. Make sure all the connections on the EVB are correct, then turn on power supply and E-load. The part starts to operate. TABLE Typical Maximumu IOUT Values VIN V VOUT V 5 IOMAX mA 870 1150 Table 1 shows typical maximum IOUT values for 1.2MHz switching frequency and 10uH inductor 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 shows the ISL97516 maximum output current, IOMAX in different input and output voltages.
