Description

The 5093MTC is a synchronous two-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for VRM 9.x processors. Two interleaved synchro
nous 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.
 
The FAN5093 features Programmable Active Droop for transient response with minimum output capacitance. It has integrated high-current gate drivers, with adaptive delay gat
switching, eliminating the need for external drive devices. The FAN5093 uses a 5-bit D/A converter to program the output voltage from 1.10V to 1.85V in 25mV steps with an accuracy of 1%. The FAN5093 uses a high level of integration to deliver load currents in excess of 50A from a 12V source with minimal external circuitry.
