Description
The FAN5093 is a synchronous multi-phase DC-DC control-
ler IC which provides a highly accurate, programmable out-
put 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. The FAN5093 fea-
tures remote voltage sensing and Programmable Active
Droop for 100nsec converter transient response with mini-
mum output capacitance. It has integrated high-current gate
drivers, with adaptive delay gate 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 0.5%. The
FAN5093 uses a high level of integration to deliver load cur-
rents in excess of 50A from a 12V source with minimal
external circuitry. The FAN5093 also offers integrated func-
tions including Power Good, Output Enable/Soft Start,
under-voltage lockout,
over-voltage protection, and adjustable current limiting with
independent current sense on each phase. It is available in a
24 pin TSSOP package.
