ISL6334CRZ

VR11.1, 4-Phase PWM Controller with Light Load Efficiency Enhancement and Load Current Monitoring Features

The ISL6334CRZ control microprocessor core voltage regulation by driving up to 4 interleaved synchronous-rectified buck channels in parallel. This multiphase architecture results in multiplying channel ripple frequency and ( ISL6334CRZ ) reducing input and output ripple currents. Lower ripple results in fewer (ISL6334CRZ ) components, lower cost, reduced power dissipation, and smaller implementation area

Microprocessor loads can generate load ( ISL6334CRZ ) transients with extremely fast edge rates and requires high efficiency at light load. The رISL6334CRZ  utilizes Intersil’s proprietary Active Pulse Positioning (APP), Adaptive Phase Alignment (APA) modulation scheme, active phase adding and dropping to achieve and maintain the extremely fast transient ( ISL6334CRZ ) response with fewer output capacitors and high efficiency from light to full load

The ISL6334CRZ  is designed to be ( ISL6334CRZ ) completely compliant with Intel VR11.1 specifications. It accurately reports the load current via IMON pin to the microprocessor, which sends an active low PSI# ( ISL6334CRZ  ) signal to the controller at low power mode. The controller then enters 1- or 2-phase operation with diode ( ISL6334CRZ ) emulation option to reduce magnetic core and switching losses, yielding high efficiency at light load. After the PSI# signal is de-asserted, the dropped phase(s) are added back to sustain heavy ( ISL6334CRZ ) load transient response and efficiency

.Features

Adjustable Switching ( ISL6334CRZ ) Frequency up to 1MHz Per Phase

Integrated Programmable (ISL6334CRZ ) Temperature Compensation

Integrated Open ( ISL6334CRZ) Sense Line Protection
