DescriptionThe FAN5090 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 FAN5090 features Programmable Active Droop
for
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.
The FAN5090 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 FAN5090 uses a high level of integra-
tion to deliver load currents in excess of 50A from a 12V
source with minimal external circuitry.
The FAN5090 also offers integrated functions including
Power Good, Output Enable/Soft Start, under-voltage lock-
out, over-voltage protection, and adjustable current limiting
with independent current sense on each phase. It is available
in a 24 pin TSSOP package.
