1 / 3 page Product Description The PI3751-00 is a high efficiency, wide input range DC-DC ZVS-Buck-Boost regulator. This high density module integrates controller, power switches, and support components. The integration of a high performance Zero- Voltage Switching (ZVS) topology, within the PI3751-00, increases point of load performance providing best in class power efficiency. The PI3751-00 requires an externally applied 5 V bias to the VDR input, an external inductor, resistive divider and minimal capacitors to form a complete DC-DC switching mode buck-boost regulator. The ZVS architecture also enables high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients. The PI3751-00 sustains high switching frequency up to the rated input voltage without sacrificing efficiency and supports large conversion ratios. Features • Over 97.5% efficiency at 2.5 MHz FSW • Wide input voltage range of 38 V to 60 V • Wide output voltage range of 38 V to 50 V • Up to 200 W continuous output power / 368 W peak • Power density exceeding 9,150 W/in3 • Fast transient response in VRM 12.X applications • Light load mode < 200 mW no load power dissipation • VTM compatibility mode • High side current sense amplifier • User configurable differential amplifier • Input / Output Over / Under Voltage Protection • Temperature lockout protection • Fast and slow current limits • -40°C to 125°C operating range (TJ) Applications • Factorized Power Solution (when coupled with a VTM® device) • Computing, Communications, Precessor, DDR Memory • 48 V to POL Power Solutions Package Information • 10 mm x 14 mm x 2.56 mm Land Grid Array Module Cool-Power® Rev 1.0 vicorpower.com Page 1 of 3 12/2014 800 927.9474 38 V to 60 Vin, 200 W Cool-Power ZVS Buck-Boost Cool-Power® PI3751-00 Typical Application Applications Diagram for use within a Factorized Power, VR12.5 Design |
