NDQ900 Series Quarter-Brick
The NDQ900 non-isolated single-output digitally controlled DC-DC converter has a standard quarter-brick outline and pin configuration. From an input voltage ranging over 40 to 60 VDC, the converter outputs up to 900 W at 12.25 VDC, reaching an ultra-high peak efficiency of 96.7%. Noise/ripple is 50 mV pk-pk typical with a 4 mF electrolytic capacitor. An ideal choice for 48 V to 12 V down conversion in high-power computing and storage applications, the NDQ900 outputs full power over an operating temperature range of -40 to +85°C with forced air cooling. An optional PMBus® interface makes for flexible digital control and monitoring.
