Quad-Output Controller for
Low-Power Architecture
General Description
The MAX17017 is a quad-output controller for ultra-
mobile portable computers (UMPCs) that rely on a low-
power architecture. The MAX17017 provides a compact,
low-cost controller capable of providing four indepen-
dent regulators—a main stage, a 3A P-P internal step-
down, a 5A P-P internal step-down, and a 2A source/sink
linear regulator.
The main regulator can be configured as either a step-
down converter (for 2 to 4 Li+ cell applications) or as a
step-up converter (for 1 Li+ cell applications). The inter-
nal switching regulators include 5V synchronous
MOSFETs that can be powered directly from a single Li+
cell or from the main 3.3V/5V power stages. Finally, the
linear regulator is capable of sourcing and sinking 2A to
support DDR termination requirements or to generate a
fixed output voltage.
The step-down converters use a peak current-mode,
fixed-frequency control scheme—an easy to implement
architecture that does not sacrifice fast-transient
response. This architecture also supports peak current-
limit protection and pulse-skipping operation to maintain
high efficiency under light-load conditions.
Separate enable inputs and independent open-drain
power-good outputs allow flexible power sequencing. A
soft-start function gradually ramps up the output volt-
age to reduce the inrush current. Disabled regulators
enter high-impedance states to avoid negative output
voltage created by rapidly discharging the output
through the low-side MOSFET. The MAX17017 also
includes output undervoltage, output overvoltage, and
