ISL97519AIUZEVALZ

USER’S MANUAL ISL97519AIUZEVALZ AN1645 Rev.1.00 Mar 3, 2022 Description Quick Setup Guide The ISL97519AIUZEVALZ evaluation board is an evaluation kit for evaluating the ISL97519AIUZEVALZ, a step-up voltage regulator that operates with high frequency and high efficiency. This evaluation kit is designed to deliver over 90% efficiency. Step 1: Connect the power supply between the headers of VIN and GND. The positive output of the power supply should be connected to the VIN header. Set the power supply voltage between 2.3V and 5V, and the current limit at 3A. The ISL97519AIUZEVALZ kit provides a dip switch that allows users to select either 600kHz or 1.2MHz switching frequency. Step 2: Connect the E-load between the headers of VOUT and GND. The positive input of the E-load should be connected to the VOUT header. Set the E-load current. The load current should not exceed the maximum output current that the part can supply. Key Features • A Complete Evaluation Platform for Evaluation of ISL97519A • Input Voltage: 2.3V to 5.5V • Proven Evaluation Board Layout • Pb-free (RoHS Compliant) Step 4: Close pins 2 and 3 of S1 to tie the EN pin to VIN in order to enable the part. To disable the part, open pins 2 and 3 in order to pull EN to ground with R3 to disable the part.

This will set the switching frequency to 1.2MHz. Open pins 1 and 4 to pull FSEL to ground with R4 to set the frequency to 600kHz. DESCRIPTION Evaluation Board for ISL97519A Make sure all the connections on the evaluation board are correct, then turn on the power supply and E-load. The part will start to operate. Maximum Output Current The MOSFET current limit is normally 2.0A and guaranteed at 1.7A. This restricts the maximum output current that the ISL97519A can drive. Table 1 shows the ISL97519AIUZEVALZ maximum output current, IOMAX at different input and output voltages. TABLE 1.
