The correct equipment connections and measurement points are shown in Table 3 Table 3. Standard Configuration Jumper Connections Jumper Position J6 Jumper from pin 1 to pin 2 Power Supply - Ammeter 1 + A COM Voltmeter 1 V COM Voltmeter 2 V COM Ammeter 2 A COM Electronic Load + - Figure 3. Test Setup 4.2 Test Equipment Power Supply: The input voltage source (VIN) should be a variable supply capable of 0V to 20V and source at least 15A. Multi-meters: • Voltmeter 1: Input voltage, connect from VIN to VIN• Voltmeter 2: Output voltage, connect from VOUT to GND • Ammeter 1: Input current, must be able to handle 15A. Shunt resistor can be used as needed. • Ammeter 2: Output current, must be able to handle 2A. Shunt resistor can be used as needed. Electronic Load: The load should be constant resistance (CR) or constant current (CC) capable. It should safely handle 2A at 24V. Oscilloscope: 20-MHz bandwidth and AC coupling. Measure the output voltage ripple directly across an output capacitor with a short ground lead. It is not recommended to use a long-leaded ground connection due to the possibility of noise being coupled into the signal. To measure other waveforms, adjust the oscilloscope as needed. 5 Test Results Figure 4 through Figure 19 present the typical performance of the LM5155EVM-BST according to the BOM and the configuration described in Section 4. Based on measurement techniques and environmental variables measurements might differ slightly than the data presented.
