Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, VI = 27 V,
IO = 2 A resistive load.
Top trace: output voltage (1.0 V/div.).
Bottom trace: input voltage (10 V/div.).
Time scale: (2 ms/div.).
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, VI = 27 V,
IO = 2 A resistive load.
Top trace: output voltage (1.0 V/div.).
Bottom trace: input voltage (10 V/div.).
Time scale: (2 ms/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 27 V,
IO = 2 A resistive load.
Trace: output voltage (5 mV/div.).
Time scale: (2 μs/div.).
Output voltage response to load current step-
change (0.5-1.5-0.5 A) at:
Tref =+25°C, VI = 27 V.
Top trace: output voltage (200 mV/div.).
Bottom trace: load current (1 A/div.).
Time scale: (0.2 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:
Rou= 3.18 x (3.9 — Vo) / ( Vo - Voi) kΩ
E.g. Increase 4% =>Vout =3.43 Vdc
3.18 x (3.9 — 3.43) / (3.43- 3.3) = 11.5 k
Ω
Output Voltage Adjust Downwards, Decrease:
Rod= 17.2 x ( Voi — Vo) / (Vo —1.7) kΩ
E.g. Decrease 2% =>Vout = 3.23 Vdc
17.2 x ( 3.3 — 3.23) / (3.23 —1.7)= 0.79 kΩ
E
