7.2 V Typical Characteristics
PKM 4116D PINB
Start-up
Shut-down
Start-up enabled by connecting VI at:
Tref = +25°C, IO = 15 A resistive load,
VI = 53 V.
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (20 V/div.).
Time scale: 2 ms/div..
Shut-down enabled by disconnecting VI at:
Tref = +25°C, IO = 1.5 A resistive load,
VI = 53 V
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (20 V/div.).
Time scale: 0.5 ms/div..
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple (20mV/div.) at:
Tref = +25°C, IO = 15 A resistive load,
VI = 53 V. Time scale: 1 s/div.
See the filter in the Output ripple and noise section (EMC
Specification).
Output voltage response to load current step-change
(3.75-11.25-3.75 A) at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage (200mV/div.).
Bottom trace: load current (5.0 A/div.).
Time scale: {0.2 ms/div.}.
Output Voltage Adjust (see operating information)
Passive trim
The resistor value for an adjusted output voltage is calculated by using
the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= 5.11((7.2(100+Δ%))/1.225Δ%-(100+2Δ%)/Δ%) kOhm
Eg Increase 4% =>V
out =7.488 Vdc
5.11(7.2(100+4)/1.225x4-(100+2x4)/4 = 642 kOhm
Output Voltage Adjust Downwards, Decrease:
Radj= 5.11(100/Δ%-2) kOhm
Eg Decrease 2% =>V
out = 7.056 Vdc
5.11(100/2-2)= 245 kOhm
The PKM4000D series DC/DC converters can be offered with a
baseplate. Baseplate helps to cool hotspots more efficient during
heavy load. The baseplate have approximately 5°C improved
derating compared to datasheet showing non baseplated PKM4000D.
The baseplate is intended to be mounted on a cold wall to transfer
heat away from the converter. By mounting PKM4000D in this way
thermal derating can be improved by more than 10°C .
