Single Phase IMVP-IV Controller for Intel Pentium M ISL6218CVZ
The ISL6218 Single-Phase Buck PWM control IC, with integrated half bridge gate driver, provides a precision voltage regulation system for advanced Pentium-M microprocessors in notebook computers. This control IC also features both input voltage feed-forward and average current mode control for excellent dynamic response, "Loss-less" current sensing using MOSFET rsubDS(ON)/sub, and user selectable switching frequencies from 250kHz to 500kHz per phase.brbr The ISL6218 includes a 6-bit digital-to-analog converter (DAC) that dynamically adjusts the CORE PWM output voltage from 0.700V to 1.708V in 16mV steps, and conforms to the Intel IMVP-IV™ mobile VID specification. The ISL6218 also has logic inputs to select Active, Deep Sleep and Deeper Sleep modes of operation. A precision reference, remote sensing and proprietary architecture with integrated processor-mode compensated "Droop" provides excellent static and dynamic CORE voltage regulation.brbr Another feature of the ISL6218 IC controller is the internal PGOOD delay circuit that holds the PGOOD pin low for 3ms to 12ms after the VCCP and VCC_MCH regulators are within regulation. This PGOOD signal is masked during VID changes. Output overvoltage and undervoltage are monitored and result in the converter latching off and PGOOD signal being held low.brbr The overvoltage and undervoltage thresholds are 112% and 84% of the VID, Deep or Deeper Sleep setpoint. Overcurrent protection features a 32 cycle overcurrent shutdown. PGOOD, Overvoltage, Undervoltage and Overcurrent provide monitoring and protection for the microprocessor and power system. The ISL6218 IC is available in a 38 Ld TSSOP and 40 Ld QFN package.
