• Manufacturer Part Number: cf48240qtc06nrs-g
• Description: Quarter-brick Dc-dc Converter
• Manufacturer: SynQor Worldwide Headquarters

Product # CF48xxxQTXxx
Figure 1: Efficiency at nominal output voltage vs. load current for minimum,
nominal, and maximum input voltage at 25°C.
Figure 3: Open Frame converter max. output power derating vs. ambient air
temperature for airflow rates of 100 LFM through 400 LFM. Air flows across the
converter from input to output (nominal input voltage).
Figure 5: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.1A/µs). Load cap: 15µF tantalum cap and 1µF
ceramic cap. Ch 1: Vout, Ch 2: Iout.
