FAN5094  
Multi-Phase Interleaved Buck Converter  
Features  
Description  
• Programmable output from 1.100V to 1.850V in 25mV  
steps using an integrated 5-bit DAC  
The FAN5094 is a synchronous multi-phase DC-DC  
controller IC which provides a highly accurate,  
• Two interleaved synchronous phases per IC for maximum  
performance  
• Up to 4 phase power system  
• Built-in current sharing between phases and between ICs  
• Frequency and phase synchronization between ICs  
• Remote sense and Programmable Active Droop™  
• High precision voltage reference  
• High speed transient response  
• Programmable frequency from 200KHz to 2MHz  
• Adaptive delay gate switching  
• Integrated high-current gate drivers  
• Integrated Power Good, OV, UV, Enable/Soft Start  
functions  
programmable output voltage for all high-performance  
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. FAN5094s can be paralleled while maintaining  
both frequency and phase synchronization and ensuring  
current sharing in a high-power system. The FAN5094  
features remote voltage sensing, Programmable Active  
Droopand advanced response for optimal converter  
transient response with minimum output capacitance. It has  
integrated high-current gate drivers with adaptive delay gate  
switching, eliminating the need for external drive devices.  
These make it possible to create power supplies running at a  
switching frequency as high as 4MHz, for ultra-high density.  
The FAN5094 uses a 5-bit D/A converter to program the  
output voltage from 1.100V to 1.850V in 25mV steps with  
an accuracy of 0.5%. The FAN5094 uses a high level of  
integration to deliver load currents in excess of 150A from a  
12V source with minimal external circuitry. The FAN5094  
also offers integrated functions including Power Good,  
Output Enable/Soft Start, under-voltage lockout, over-  
voltage protection, and current limiting with independent  
current sense on each phase. It is available in a 28-pin  
TSSOP package.  
• Drives N-channel MOSFETs  
• Operation optimized for 12V operation  
• High efficiency mode at light load  
• Overcurrent protection using MOSFET sensing  
• 28 pin TSSOP package  
Applications  
• Power supply for Pentium®IV  
• Power supply for Athlon®  
• Power supply for Ultrasparc™  
• VRM for Pentium IV processor  
• Programmable step-down power supply
