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 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382 PART NUMBER: VFB200 page 4 of 4 date 1/11/2008 DESCRIPTION: full brick dc-dc converter 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. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382
