Applications with AUTO Phase Shedding
ISL6364A Features The ISL6364A is a dual PWM controller; its 4-phase PWMs
control the microprocessor core or the memory voltage
regulator, while its single-phase PWM controls the peripheral
voltage regulator for graphics, system agent, or processor I/O. Intel VR12/IMVP7 Compliant
-SerialVID with Programmable IMAX, TMAX, BOOT,
ADDRESS OFFSET Registers The ISL6364A utilizes Intersil’s proprietary Enhanced Active
Pulse Positioning (EAPP) modulation scheme to achieve
extremely fast transient response with fewer output capacitors. Intersil’s Proprietary Enhanced Active Pulse Positioning
(EAPP) Modulation Scheme (Patented)
-Variable Frequency Control During Load Transients to
Reduce Beat Frequency Oscillation
-Linear Control with Evenly Distributed PWM Pulses for
Better Phase Current Balance During Load Transients
-Voltage Feed-Forward and Adjustable Ramp Options
-High Frequency and PSI Compensation Options NVM and Firmware Free for Low Cost and Easy Use Auto Phase Shedding Option for Greener Environment with
Boot-refresh Option Dual Outputs
-Output 1 (VR0): 1 to 4-Phase for Core or Memory (Coupled
Inductor and Phase Doubler, ISL6617/11A Compatible)
-Output 2 (VR1): Single Phase for Graphics, System Agent,
or Processor I/O (Phase Doubler Compatible, EN = HIGH) …
