FET + buck converters suit 12-V input rails

The MIC2405x SuperSwitcher II family of integrated MOSFET buck regulators are optimized for 12-V input rails (4.5 to 19 V), with 6-, 9-, and 12-A output supply current. The MIC2405x family is comprised of six common-footprint, DC-to-DC buck regulators that leverage the proprietary HyperSpeed control and HyperLight load architectures.

The buck regulators provide more than 95% peak efficiency and operate at 600-kHz switching frequency with ±1% of output voltage accuracy (with output adjustable down to 0.8 V). The devices provide solutions for distributed power systems, communications networking and infrastructure, and industrial applications. They are available in MLF-28, 5 x 6-mm packages. (Ea/1,000: MIC24051/2 (6A), $0.91; MIC24053/4 (9A), $1.04; MIC24055/6 (12A), $1.22 – available now.)
