General Description
The FAN5019 is a multi-phase DC-DC controller for imple-
menting high-current, low-voltage, CPU core power regula-
tion circuits. It is part of a chipset that includes external
MOSFET drivers and power MOSFETS. The FAN5019
drives up to four synchronous-rectified buck channels in par-
allel. The multi-phase buck converter architecture uses inter-
leaved switching to multiply ripple frequency by the number
of phases and reduce input and output ripple currents. Lower
ripple results in fewer components, lower component cost,
reduced power dissipation, and smaller board area.
The FAN5019 features a high bandwidth control loop to
provide optimal response to load transients. The FAN5019
senses current using lossless techniques: Phase current is
measured through each of the output inductors. This current
information is summed, averaged and used to set the loadline
of the output via programmable "droop". The droop is tem-
perature compensated to achieve precise loadline character-
istics over the entire operating range. Additionally,
individual phase current is measured using the RDS(ON) of
the low-side MOSFETs. This information is used to dynam-
ically balance/steer per-phase current. The phase currents
are also summed and averaged for over-current detection.
Dynamic-VID technology allows on-the-fly VID changes
with controlled, glitch-less output. Additionally, short-circuit
protection, adjustable current limiting, over-voltage protec-
tion and power-good circuitry combine to ensure reliable and
safe operation. The operating temperature range is 0°C to
+85°C and the operating voltage is a single +12V supply,
which simplifies the design. The FAN5019 is available in a
TSSOP-28 package.
