  • The PM6641 is a monolithic voltage regulator module specifically designed to supply DDR2/3 memory and chipset in ultra-mobile PC and real estate constrained portable systems.

    It integrates three independent, adjustable, constant frequency buck converters, a ±2 Apk low drop-out (LDO) linear regulator and a ±15 mA low noise buffered reference.
    Each regulator provides basic UV and OV protections, programmable soft-start and current limit and active soft-end.
    Pulse-skipping technique is performed to increase efficiency at very light load.

    主要特性

    • Separate Power Good signals
    • Selectable tracking discharge for VDDQ
    • Programmable current limit and soft-start for all outputs
    • Pulse skipping at light load
    • Thermal protection
    • Latched OVP, UVP protection
    • S0-S5 states compliant DDR2/3 section
    • ±2 Apk LDO for DDR2/3 termination (VTT) with foldback
    • 0.8 V ±1% internal voltage reference
    • Fast response, constant frequency, current mode control
    • 2.7 V to 5.5 V input voltage range
    • Low noise DDR2/3 reference (VTTREF)
    • Active soft-end for all outputs
    • Three independent, adjustable, out-of-phase SMPS for DDR2/3 (VDDQ) and chipset supply
