Test Procedure for the CS5171/CS5173 Evaluation Board
Figure 1: Test Setup
The following steps describe the test procedure for all these boards:
Suggested Equipment:
Current limited DC Power Supply (e.g. AGILENT 6645A) ……………………… 1pc
DC Volt-Meter able to measure up to 60 V DC (e.g. KEITHLEY 2000) ………… 2pcs
DC Amp-Meter able to measure up to 2 A DC (e.g. KEITHLEY 2000) ………......1pc
DC Amp-Meter able to measure up to 5 A DC (e.g. FLUKE 89 IV)……………… 1pc
DC Electronic Load (e.g. KIKUSUI PLZ153WH) ………………………………... 1pc

Test Procedure:
1. Connect the test setup as shown in Figure 1.
2. Apply an input voltage, VIN = 12 Vdc
3. Apply IOUT(load) = 0 A
4. Check that VOUT = 200V + 5%Vdc
5. Set IOUT to desired level 0 mA- 20 mA and measure voltage and current. The efficiency should be similar to that shown
in Figure 3 and 4.
6. Check that VOUT = 200V + 5%Vdc under desired operating condition
7. Turn off the load
8. Turn off VIN
9. End of the test
