28.2 V/12.4 A Typical Characteristics
PKJ 4316 API
Start-up
Shut-down
Start-up enabled by connecting VI at:
Tref = +25°C, VI = 53 V,
IO = 12.4 A resistive load.
Top trace: output voltage (10 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (5 ms/div.).
Shut-down enabled by disconnecting VI at:
Tref = +25°C, VI = 53 V,
IO = 12.4 A resistive load.
Top trace: output voltage (10 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (5 ms/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
IO = 12.4 A resistive load.
Trace: output voltage (20 mV/div.).
Time scale: (2 s/div.).
Output voltage response to load current step-
change (3.1-9.3-3.1 A) at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage (1 V/div.).
Bottom trace: load current (5 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:
