Infineon Technologies 3D IPOL power module

Integrated point-of-load 3 A or 4 A single output high efficiency buck regulator module with integrated inductor.

The TDM3883 / TDM3885 IPOL power module with an integrated inductor is an easy-to-design, fully integrated 3 A buck converter. It offers a high-efficiency load and line regulation over a wide input supply range with a compact design. With integrated inductor and capacitors, it reduces external components and saves 80% of PCB area. Therefore, TMD3883 / TDM3885 allows a much higer power density while minimizing the parasitic parameters.
