When operating the VHB150, proper derating or cooling is needed. Following is the derating curve of VHB150 without heat sink. V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258 4/4 VHB150 Half Brick DC-DC Converter Rev. 09-2007 Remote ON/OFF Control The VHB150 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB150 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 10F tantalum capacitor and a 1.0F ceramic capacitor across the output.
