Description
Description
The FAN5090 is a synchronous two-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for VRM 9.x processors. Two interleaved synchronous buck regulator phases with built-in current sharing operate 180° out of phase to provide the fast transient response needed to satisfy high current applications while minimizing external components.
Features
• Programmable output from 1.10V to 1.85V in 25mV steps using an integrated 5-bit DAC
• Two interleaved synchronous phases for maximum performance
• 100nsec transient response time
• Built-in current sharing between phases
• Remote sense
• Programmable Active Droop (Voltage Positioning)
• Programmable switching frequency from 100KHz to 300KHz per phase
• Adaptive delay gate switching
• Integrated high-current gate drivers
• Integrated Power Good, OV, UV, Enable/Soft Start functions
• Drives N-channel MOSFETs
• Operation optimized for 12V operation
• Overcurrent protection using MOSFET sensing
• 24 pin TSSOP packageApplications
• Power supply for Pentium® IV
• Power supply for Athlon®
• VRM for Pentium IV processor
• Programmable step-down power supply
