The LMZM23601 is a MicroSiP step-down dc-dc converter that converts a 4- to 36-V dc input to a lower dc voltage with a maximum output of up to 1 A.

This article discusses a new power supply topology IFB 3 Interleaved Full-Bridge Boost Buck for DC-DC converters to meet these demands. 3A igh-Efficiency DC-DC Step-Down SiP Power Module with Integrated Inductor. Historically buck converters have relied on high-Q inductors on the order of 1 to 100 muH to achieve high efficiency.

The dramatic decrease in the inductance value is made possible by the unique bridge timing of the stacked design that causes magnetic coupling to boost the converters efficiency by. Inductor efficiency is defined as results for inductor performance up to 100 MHz and also ind PoutPout Ploss 1 presents results for the use of the inductors in a 20 MHz dc-dc converter. Fully Integrated DC-DC Converters.
