FAN5231 Product details

Description
The FAN5231 is a highly integrated power controller, which provides a complete power management solution for mobile CPUs. The IC integrates two PWM controllers and a linear regulator as well as monitoring and protection circuitry into a single 28-lead plastic SSOP package. The two PWM controllers regulate the microprocessor core and I/O voltages with synchronous-rectified buck converters, while the linear regulator powers the CPU clock.

Features
• Provides 3 Regulated Voltages
    – Microprocessor core (SpeedStep™-enabled)
    – Microprocessor I/O
    – Microprocessor Clock Generator
• High Efficiency Over Wide Load Range
• Not Dissipative Current-Sense Scheme
    – Uses MOSFET’s RDS(ON)
    – Optional Current-Sense Resistor for Precision Overcurrent
• Adaptive Dead Time Drivers for N-Channel MOSFETs
• Operates from +5V, +3.3V and Battery (5.6-24V) Inputs
• Precision Core Voltage Control:
    – Remote “Kelvin” Sensing
    – Summing Current-Mode Control
    – On-Chip Mode-Compensated “Droop” for Optimum Transient Response and Lower Processor Power Dissipation
• TTL-Compatible 5-Bit Digital Output Voltage Selection
    – Wide Range - 0.925VDC to 1.3VDC in 25mV Steps, and from 1.3VDC to 2.0VDC in 50mV Steps
    – Programmable “On-the-Fly” VID code change with customer programmable slew rate and 100ms settling time
• Power-Good Output Voltage Monitor
• No negative Core and I/O voltage on turn-off
• Over-Voltage, Under-Voltage and Over-Current Fault Monitors
• 300kHz Fixed Switching Frequency
• Thermal Shut-Down

Applications
• Converters for Mobile Dual-Mode CPUs
• Web Tablets
• Internet Appliances
