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)

:
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
