A
1.5 V/14 A Typical Characteristics
PKD 4218HE SI
Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 14 A resistive load.
Top trace: output voltage (0.5 V/div).
Bottom trace: input voltage (20 V/div).
Time scale: 2 ms/div.
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, VI = 53 V,
IO = 14 A resistive load.
Top trace: output voltage (0.5 V/div).
Bottom trace: input voltage (50 V/div).
Time scale: 0.2 ms/div.
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
IO = 14 A resistive load.
Trace: output voltage (20mV/div).
Time scale: 2 s/div.
Output voltage response to load current step-
change (3.5-10.5-3.5 A}) at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage (200mV/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:
Radj= 6 / ((Vout / 1.5) - 1) - 40 k
Example: Increase 4% =>Vout = 1.56 Vdc
6 / ((1.56 / 1.5 ) - 1) — 40 = 110 k
Output Voltage Adjust Downwards, Decrease:
Radj= ((15 x Vout — 9) / (1.5 — Vout )) — 40 k
Example: Decrease 2% =>Vout = 1.47 Vdc
((15 x 1.47 — 9) / (1.5 — 1.47)) — 40 = 395 k
E
