Product Description

The PI3740-00 is a high-efficiency, wide input and output

range DC-DC ZVS Buck-Boost Regulator. This high-density

System?in?Package (SiP) integrates controller, power switches,

and support components. The integration of a high-performance

Zero?Voltage Switching (ZVS) topology within the PI3740-00

increases point-of-load performance, providing best-in-class

power efficiency.

The PI3740-00 requires 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 fast

dynamic response to line and load transients.
