description
ISL6367 is a hybrid digital dual PWM controller designed to meet the Intel VR12/IMVP7 specification. Stage 6 PWM controls the microprocessor as the core, memory voltage regulator, while its single-phase PWM controls graphics, system agent, or processor I/O peripheral regulation It includes programmable functions for ease of use and telemetry, high system flexibility and overclocking applications using SMBus, PMBus protocol, or Mi2C interface (modification), the purpose of which is to conflict with the CPU's SVID bus. This hybrid digital approach eliminates the non-volatile memory and firmware requirements common in 1 all-digital solutions and significantly reduces design complexity, inventory and manufacturing costs. The ISL6367 uses Intersil's proprietary Enhanced Aortic Pulse Localization (EAPP) modulation scheme to achieve extremely fast transient response with fewer output capacitors. ISL6367 accurately monitors the load current through the IMON pin and reports this information through the IOUT-registered microprocessor, which sends a PSI # signal in low-power mode through the SVID bus controller. The controller enters phase 1 - or 2 to operate in low power mode (PSI1); In ultra-low power mode (PSI2,3), it operates in single phase with diode emulation options. In low-power mode, core and switching losses are significantly reduced, resulting in high efficiency at light loads. After the PSI# signal is pulled up, the falling phase (S) is added back to withstand heavy load transient response and efficiency. In addition, the ISL6367 function phase automatically sheds from light to fully loaded green environments to optimize efficiency without sacrificing transient performance. Today's microprocessors require a strictly regulated output voltage position and load current (sag). ISL6367 senses, the voltage is continuously output by measuring the voltage by a dedicated current-sense resistor or the DCR of the output inductor. The FB pin that senses the outflow of the inductive current develops sag to control the precision voltage drop of the feedback resistor. The current sense circuitry also provides the required signal channel current balancing, average overcurrent protection, and individual phase current limiting. The trademark and TMS pins sense the temperature of a 1 negative temperature coefficient (NTC) thermistor, which is an internal thermal monitoring and thermal compensation digitization that integrates the current sense elements of the respective voltage regulators. The ISL6367 perceivable input current provides 1 output that qualifies for true catastrophic fault protection. It also features remote voltage detection and completely eliminates the potential difference between any remote and local justifications. This improves the accuracy of regulation and protection. Threshold-sensitive enabling inputs can accurately coordinate ISL6367 start-up with other voltages.
