DESCRIPTION: half brick dc-dc converter 3 of 4 PART NUMBER: VHB50W Series Application Notes Derating: The operating case temperature range of the VHB50 series is -40°C to +100°C. When operating the VHB50, proper derating or cooling is needed. Following is the derating curve of VHB50 without heat sink.
DESCRIPTION: half brick dc-dc converter 4 of 4 PART NUMBER: VHB50W Series 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 10 μF tantalum capacitor and a 1.0 μF ceramic capacitor across the output. Remote ON/OFF Control The VHB50 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB50 series is available with “positive logic” or “negative logic” options.
