Test Procedure for the LV58063MCGEVB Evaluation Board The following steps detail the basic test procedure for all these boards: Necessary Equipment: DC Power Supply (e.g. ADVANTEST R6243 DC Voltage Current Source/Monitor) : 1pcs Electronic Load (e.g. FUJITSU ACCESS LIMITED Electric Load EUL-150αXL) : 1pcs Oscilloscope (e.g. LeCroy WaveJet ) : 1pcs Digital Multimeter (able to measure up to 30V and 5A) : 1pcs or more Test Procedure: 1. Setup of the TEST: Connect the test setup as shown in Figure1 2. VOUT Check1: Apply an input voltage, VIN = 12-24 Vdc Apply IOUT (load) = 0 A (CR MODE) Check that VOUT = 3.3V ±5% Vdc (under desired operating condition) 3. VOUT Check2: Apply an input voltage, VIN = 24 Vdc Apply IOUT (load) = 0-3 A (CR MODE) Check that VOUT = 3.3V ±5% Vdc (under desired operating condition) 4. Current limit Check: Apply IOUT (load) = 3.5 A or more (CR MODE) Check that VOUT =2Vdc and under (about 1V) 5. EN Check: Apply an input voltage, VIN=24Vdc, IOUT (Load) = 1A, Connect EN Pin to GND. Check that VOUT =0Vdc Check that IIN = 0.1mA and under 6. End of the TEST: Turn off the load, Turn off VIN 5/9/2014 1 www.onsemi.com
