Description
The FAN5091 is a synchronous multi-slice DC-DC controller
IC which provides a highly accurate, programmable output
voltage for all high-performance processors. Two interleaved
synchronous buck regulator slices with built-in current shar-
ing operate 180° out of phase to provide the fast transient
response needed to satisfy high current applications while
minimizing external components. The FAN5091 features
remote voltage sensing and Programmable Active Droop
for 100nsec converter transient response with minimum out-
put capacitance. It has integrated high-current gate drivers,
with adaptive delay gate switching, eliminating the need for
external drive devices. The FAN5091 uses a 5-bit D/A con-
verter to program the output voltage from 1.10V to 1.85V in
25mV steps with an accuracy of 1%. The FAN5091 uses a
high level of integration to deliver load currents in excess of
50A from a 5V source with minimal external circuitry. The
FAN5091 also offers integrated functions including Power
Good, Output Enable/Soft Start, under- voltage lockout,
over-voltage protection, and adjustable current limiting with
independent current sense on each slice. It is available in a
24 pin TSSOP package.
