1.8 V/25 A Typical Characteristics
PKB 4418 PINB
Start-up
Shut-down
Start-up enabled by connecting VI at:
T
ref = +25°C, VI = 53 V,
I
O = 25 A resistive load.
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (5 ms/div.).
Shut-down enabled by disconnecting VI at:
T
ref = +25°C, VI = 53 V,
I
O = 25 A resistive load.
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (0.1 ms/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
T
ref = +25°C, VI = 53 V,
I
O = 25 A resistive load.
Trace: output voltage (20 mV/div.).
Time scale: (2 s/div.).
Output voltage response to load current step-
change (6.25-18.75-6.25 A) at:
T
ref =+25°C, VI = 53 V.
Top trace: output voltage (200 mV/div.).
Bottom trace: load current (10 A/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:
