PKB 4711 PINB - Typical Characteristics
Output voltage ripple (20mV/div.) at TPcb = +25 °C, VI = 53 V,
IO = 15 A resistive load with C = 10
F tantalum and 0.1 F
ceramic capacitor.
Band width = 20 MHz. Time scale: 2 s/div.
Output voltage response to load current step-change
(3.75-11.25-3.75 A) at TPcb=+25 °C, Vin=53 V.
Top trace: output voltage (100mV/div.).
Bottom trace: load current (3.75 A/div.)
Time scale: 0.1 ms/div.
Output Voltage Adjust
Output voltage adjust resistor value vs.
percentage change in output voltage.
Output Voltage Adjust
The resistor value for an adjusted output voltage is calcu-
lated by using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= 5.11((5(100+
%))/1.225%-(100+2%)/%) kOhm
Output Voltage Adjust Downwards, Decrease:
Radj= 5.11(100 /
%-2) kOhm
Eg Increase 4% =>Vout = 5.4 Vdc
5.11(5(100+4)/1.225x4-(100+2x4)/4) = 404 kOhm
Eg Decrease 2% =>Vout = 4.9 Vdc
5.11(100/2-2)= 245 kOhm
Start-Up
Turn-Off
Start-up at IO = 15 A resistive load at TPcb = +25 °C,
VI = 53 V. Start enabled by connecting VI.
Trace A: input voltage (20 V/div.).
Trace B: output voltage (1 V/div.).
Time scale: 10 ms/div.
Turn-off at IO = 15 A resistive load at TPcb = +25 °C,
VI = 53 V. Turn-off enabled by disconnecting VI.
Trace: output voltage (1 V/div.).
Time scale: 0.1 ms/div.
