Features & Applications

ST Microelectronics offers a complete tool line, tailored to the STEVAL-ISA050V1 Monolithic VR for Chipset and DDR2/3 Demonstration Board based on PM6641.

The STEVAL-ISA050V1 demonstration board is based on the PM6641, that is a monolithic voltage regulator module, with internal Power MOSFET, specifically designed to supply DDR2/3 memory and chipset in ultra-mobile PC and real estate 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 is provided of basic under voltage (UV) and over voltage (OV) protections, programmable soft-start and current limit, active soft-end and pulse-skipping at light loads.

Features :

  • Switching section
    • 0.8 V ±1% voltage reference
    • 2.7 V to 5.5 V input voltage range
    • Fast response, constant frequency, current mode control
    • Three independent, adjustable, SMPS For DDR2/3 (VDDQ) and chipset supply
    • S3-S5 states compliant DDR2/3 section
    • Active soft-end for all outputs
    • Selectable tracking discharge for VDDQ
    • Separate Power Good signals
    • Pulse skipping at light load
    • Programmable current limit and soft-start for all outputs
    • Latched OVP, UVP protection
    • Thermal protection
  • Reference and termination voltages (VTTREF and VTT)
    • ±2 Apk LDO for DDR2/3 termination (VTT) with fold back
    • Remote VTT output sensing
    • High-Z VTT output in S3
    • ±15 mA low noise DDR2/3 buffered reference (VTTREF)

Application :

  • Supply for ultra-mobile PC (UMPC)
