ZVS Switching Regulators
PI3740-00
8V – 60V_IN , 10V – 50V_OUT , 50 – 140W Cool-Power ZVS Buck-Boost Regulator
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.
