The FAN5092 is a synchronous multi-slice DC-DC controller IC which provides a highly accurate, programmable output voltage for all high-current applications. 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. FAN5092s can be paralleled while maintaining both frequency and phase synchronization and ensuring current sharing in a high-power system. The FAN5092 features remote voltage sensing,Programmable Active Droop? and 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 output voltage can be set from 1.1V to 5V with an accuracy of 0.5%. The FAN5092 uses a high level of integration to deliver load currents in excess of 150A from a 12V source with minimal external circuitry. The FAN5092 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 slice. It is available in a 28-pin TSSOP package.
