, 150W, Cool-Power ZVS Buck-Boost Regulator
Product Description
The PI3741-0x series is a high efficiency, wide range DC-DC ZVS
Buck-Boost Regulator with two output range configurations that
utilize the same high density System-in-Package (SiP). Integrating
controller, power switches, support components and a high
performance Zero-Voltage Switching (ZVS) topology within the
PI3741-0x increases point of load performance while providing
best in class power efficiency.
The PI3741-0x requires an external inductor, resistive divider and
minimal capacitors to form a complete DC-DC switching mode
buck-boost regulator.

PI3741-00-LGIZ
PI3741-01-LGIZ
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.
