Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, I01 = I02 = 0.25 A resistive load,
VI = 53 V.
Top trace: Output 1 (5 V/div.).
Mid trace: Output 2 (5 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, I01 = I02 = 0.25 A resistive
load,
VI = 53 V.
Top trace: Output 1 (5 V/div.).
Mid trace: Output 2 (5 V/div.).
Bottom trace: input voltage (100 V/div.).
Time scale: 5 ms/div.
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple (10mV/div.) at:
Tref = +25°C, I01 = I02 = 0.25 A resistive load,
VI = 53 V. Time scale: 2 μs/div.
See the filter in the Output ripple and noise
section (EMC Specification).
Output voltage response to load current
step-change Output 1(0.1-0.2-0.1A) at:
Tref =+25°C, I02 = 0.25A , VI = 53 V.
Top trace: Output 1 (200mV/div.).
Mid trace: Output 2 (200mV/div.).
Bottom trace: Load current Output 1
(0.1 A/div.).
Time scale: 0.1 ms/div.
Output Voltage Adjust (see operating information)
Passive trim
The resistor value for an adjusted output voltage is calculated by using
the following equations:
Output Voltage Adjust Upwards, Increase:
Rou = 0.566 × (14.4 — VO)/(VO — 12) kΩ
E.g. Increase 4% =>Vout = 12.48 Vdc
0.566
× (14.4 — 12.48)/( 12.48 — 12) = 2.26 kΩ
Output Voltage Adjust Downwards, Decrease:
Rod = 2.284 × (12 — VO)/(VO — 9.52) kΩ
E.g. Decrease 2% =>Vout = 11.76 Vdc
2.284
× (12 —11.76)/(11.76 — 9.52) = 0.245 kΩ
