High-Input-Voltage Quad-Output Controller
General Description
Features
The MAX17019 is a high-input-voltage quad-output con-
troller (up to 38V). The MAX17019 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 input voltage is up to 38V. This
makes it an excellent choice for automotive applications.
The internal 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

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 MAX17019 also
includes output undervoltage, output overvoltage, and
thermal-fault protection.
The MAX17019 is available in a 48-pin, 6mm x 6mm
thin QFN package.
