    Products Detail

    PM6641TR Description


    PM6641TR is a type of monolithic voltage regulator module developed by STMicroelectronics. It is specifically designed for chipsets in ultra-mobile PC, DDR2/3 supply for ultra-mobile PC (UMPC) applications, and real estate-constrained portable systems. A suite of protection functions is provided, including basic UV and OV protections, programmable soft-start and current limit, and active soft-end. Efficiency at a very light load can be increased based on the pulse-skipping technique.



    PM6641TR Features


    Separate Power Good signals

    Pulse skipping at light load

    Programmable current limit and soft-start for all outputs

    Latched OVP, UVP protection

    Thermal protection



    PM6641TR Applications


    DDR2/3 memory and chipset supply

    UMPC and portable equipment

    Handheld and PDAs
