APPLICATION NOTES
Derating:
The operating case temperature range of the VFB200 series is -40°C to +100°C. When operating the VFB200, proper derating or cooling is needed.
Following is the derating curve of VFB200 without heat sink.
Where:
The power dissapation (Pd) is
P d= Pi - Po = Po (1-n)/n
The thermal resistance are listed below.
The temperature rise (dT):
dT = Pd * Rca

REMOTE ON/OFF CONTROL
The VFB200 series allows the user to switch the module on and off electronically with the remote on/off feature. The VFB200 series
is available with “positive logic” or “negative logic” options.
EXTERNAL OUTPUT TRIMMING
Output may optionally be externally trimmed (±10%) with a fixed resistor or an external trimpot as shown.
OUTPUT NOISE
The output noise is measured with a 10μF tantalum capacitor and a 1.0μF ceramic capacitor across the output.
