QUICK START PROCEDURE

Figure 1. Proper Measurement Equipment Setup

Refer to Figure 1 for proper measurement equipment 

setup and follow the procedure below. 
 

Note:

 When measuring the output voltage ripple, care 

must be taken to avoid a long ground lead on the oscil-

loscope probe. Measure the output voltage ripple by 

touching the probe tip and ground ring directly across 

the last output capacitor as shown in Figure 1.

1. Place SW1 to ON position.
2. With power off, connect the input power supply to 

+VIN_EMI and GND. If the EMI/EMC performance is 

not important, the input EMI filter can be bypassed by 

connecting the input power supply to +V

IN

 and GND.

3. With power off, connect loads from +V

OUT

 to GND.

4. Turn on the power at the input. Make sure that the input 

voltage does not exceeds 100V.

5. Check for the proper output voltage using a voltmeter. 

Output voltage should be within 5.0V ± 0.1V.

 

Note:

 If there is no output, temporarily disconnect the 

load to make sure that the load is not set too high.

6. Once the proper output voltage is established, adjust 

the load within the operating ranges and observe the 

output voltage regulation, ripple voltage, efficiency and 

other parameters.

7. An external clock can be added to the CLKIN terminal 

when SYNC mode is used (JP1 on the SYNC position). 

See the data sheet Frequency Selection and Phase-

Locked Loop section for details.
