FAN5019 Product details

General Description
The FAN5019 is a multi-phase DC-DC controller for implementing high-current, low-voltage, CPU core power regulation circuits. It is part of a chipset that includes external MOSFET drivers and power MOSFETS. The FAN5019 drives up to four synchronous-rectified buck channels in parallel. The multi-phase buck converter architecture uses interleaved switching to multiply ripple frequency by the number of phases and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller board area.

Features
• Pin and Function Backward Compatible with FAN53168 and FAN53180 Controllers
• Precision Multi-Phase DC-DC Core Voltage Regulation
    – ±10mV Output Voltage Accuracy Over Temperature
• Differential Remote Voltage Sensing
• Selectable 2, 3, or 4 Phase Operation
• Selectable VRM9 or VRM10 Operation
• Up to 1MHz per Phase Operation (4MHz ripple Frequency)
• Lossless Inductor Current Sensing for Loadline Compensation
    – External Temperature Compensation
• Accurate Load-Line Programming (Meets Intel® VRM/VRD10.0 and 10.X CPU Specifications)
• Accurate Channel-Current Balancing for Thermal Optimization and Layout Compensation
• Convenient 12V Supply Biasing
• 6-bit Voltage Identification (VID) Input
    – .8375V to 1.600V in 12.5mV Steps
    – Dynamic VID Capability with Fault-Blanking for glitch-less Output voltage Changes
• Adjustable Over Current Protection with Programmable Latch-Off Delay. Latch-Off Function may be Disabled
• Over-Voltage Protection – Internal OVP Crowbar Protection

Applications
• Computer DC/DC Converter VRM/VRD10.0
• Computer DC/DC Converter VRM/VRD10.X
• Computer DC/DC Converter VRM/VRD9.X
• High Current, Low Voltage DC/DC Rail
