PI3751-00
38 V to 60 Vin, 200 W Cool-Power ZVS Buck-Boost
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.
