Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 15 A resistive load.
Top trace: output voltage ( 1 V/div.).
Bottom trace: input voltage ( 50 V/div.).
Time scale: ( 2 ms/div.).
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 15 A resistive load.
Top trace: output voltage ( 1 V/div.).
Bottom trace: input voltage ( 50 V/div.).
Time scale: ( 1 ms/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
IO = 15 A resistive load.
Trace: output voltage ( 20 mV/div.).
Time scale: ( 2 s/div.).
Output voltage response to load current step-
change ( 3.75 — 11.25 -3.75 A) at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage ( 200 mV/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:
