1.8 V/60 A Typical Characteristics
PKB 4118GC PI
Start-up
Shut-down
Start-up enabled by connecting VI at:
Tp1 = +25°C, VI = 53 V,
IO = 60 A resistive load.
Top trace: output voltage (1.0 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (10 ms/div.).
Shut-down enabled by disconnecting VI at:
Tp1 = +25°C, VI = 53 V,
IO =60 A resistive load.
Top trace: output voltage (1.0 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (100 us/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tp1 = +25°C, VI = 53 V,
IO = 60 A resistive load.
Trace: output voltage (20mV/div.).
Time scale: (2 µs/div.).
Output voltage response to load current step-
change (15-45-15 A) at:
Tp1 =+25°C, VI = 53 V.
Top trace: output voltage (200mV/div.).
Bottom trace: load current (50 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:
