3.3 V Typical Characteristics
PKM 4110C PINB
Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, IO = 50 A resistive load,
VI = 53 V.
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (20 V/div.).
Time scale: 5 ms/div..
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, IO = 10 A load,
VI = 53 V
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (20 V/div.).
Time scale: 0.1 ms/div..
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple (20mV/div.) at:
Tref = +25°C, IO = 50 A resistive load,
VI = {53 V}. Time scale: 5 μs/div.
See the filter in the Output ripple and noise
section (EMC Specification).
Output voltage response to load current step-
change (12.5-47.5-12.5 A) at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage (200mV/div.).
Bottom trace: load current (12.5 A/div.).
Time scale: {0.1 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((3.3(100+Δ%))/1.225Δ%-(100+2Δ%)/Δ%) kOhm
Eg Increase 4% =>Vout =3.43 Vdc
5.11(3.3(100+4)/1.225x4-(100+2x4)/4 = 220 kOhm
Output Voltage Adjust Downwards, Decrease:
Radj= 5.11(100/Δ%-2) kOhm
Eg Decrease 2% =>Vout = 3.23 Vdc
5.11(100/2-2)= 245 kOhm
The PKM4000C 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 PKM4000C. The baseplate is intended
to be mounted on a cold wall to transfer heat away
from the converter. By mounting PKM4000C in this
way thermal derating can be improved by more
than 10°C .
