7.2Initial Power Up

1)Turn the power supply ON, set the current limit on power supply (refer to specification of either converter) and increase the input voltage (use DMM2 to monitor the voltage) until it reaches the desired value.

2)Set the switch SW1 to “OFF” position to enable the power module.

3)The converter is now operating, which can be verified by observing the DMM3 (appropriate value for the nominal output voltage) and channel 2 of the oscilloscope (appropriate value for the nominal output voltage).

4)Set the switch SW1 to the “ON” position after performing each test.

8.0Tests and Evaluation

8.1Input Characteristics

8.1.1 Input Voltage Range and Under-Voltage Lockout

The IPM04C Series of DC/DC converters will operate at full load from 3.0Vin to 5.5Vin. For the output of 3.3V, the input voltage range is from 4.0Vin to 5.5Vin. The IPM12C Series DC/DC converters will operate at full load from 8Vin to 14Vin for 12Vin (nominal) types. The converters feature input under-voltage protection, which will not allow the converter to start up unless the input voltage exceeds the turn-on voltage threshold.

Test

1)Turn on the fan.

2)Set the input voltage to the desired operating point while monitoring DMM2.

3)Set the switch SW1 to the “OFF” position to enable the converter.

4)Test the input under voltage function while observing DMM2, DMM3 and channel 1 of the oscilloscope. Increase the input voltage until the output of the converter reaches the appropriate value. This will occur between 2.40 and 2.70 volts for IPM04C modules and between 7.6 to 8.0 volts for IPM12C modules. Please refer to the appropriate converter data sheet for the detailed specification.

8.1.2 No Load Input Current Test

1)Turn on the fan.

2)Set the input voltage to the desired operating point while monitoring DMM2.

3)Set the switch SW1 to the “OFF” position to enable the converter.

4)Remove/disable the output electronic load or resistive load.

5)Note the input current from DMM1.

6)The result is the No-Load Input current of the DC/DC converter.

The No-Load Input Current will be around 20 to 85mA for the IPM12C series and around 20 to 70mA for the IPM04C series depending on the model under evaluation. (Please refer to the data sheet for the detailed specification).
