ISL6218CVZA Product details

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 rDS(ON), and user selectable
switching frequencies from 250kHz to 500kHz per phase.
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.
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.
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.
