3.3 V/50 A Typical Characteristics
PKL 4110 PIT
Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 50 A resistive load.
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (20 V/div.).
Time scale: (10 ms/div.).
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 50 A resistive load.
Top trace: output voltage (1 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 at:
Tref = +25°C, VI = 53 V,
IO = 50 A resistive load.
Trace: output voltage (50mV/div.).
Time scale: (2 μs/div.).
Output voltage response to load current step-
change (12.5-25-12.5 A) at:
Tref =+25°C, VI = 53 V.
Trace: output voltage (100mV/div.).
Time scale: (0.1 ms/div.).
Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= [(Vo(100+Δ%)/(1.225Δ%)-(100+2Δ%)/Δ%) kΩ
Eg Increase 5% =>Vout = 3.465 Vdc
3.3(100+5)/(1.225x5)-(100+2x5)/5 = 34.6 kΩ
Output Voltage Adjust Downwards, Decrease:
Radj= (100 / Δ%-2) kΩ
Eg Decrease 5% =>Vout = 3.135 Vdc
(100/5-2)= 18 kΩ
