General Description
The MAX17116 includes two current-mode 1.4MHz
switch mode power-supply (SMPS) regulators for active-
matrix organic light-emitting diode (AMOLED) displays.
The positive supply is provided by a step-up regulator
with a synchronous rectifier. The negative supply is
provided by an inverting regulator with a synchronous
rectifier.
The step-up DC-DC converter is a high-accuracy 250mA
regulator with an integrated power MOSFET switch
and synchronous rectifier. The synchronous rectifier
improves efficiency and also provides True Shutdown
TM
.
Its 4.6V (fixed) output efficiency exceeds 85% at 150mA
from a 3.7V input. A built-in, 7-bit, digital soft-start func-
tion controls startup inrush currents.
The inverting DC-DC converter is a high-accuracy
250mA regulator with a built-in power MOSFET switch
and synchronous rectifier. Its -5.4V to -1.5V output effi-
ciency exceeds 80% at 150mA from a 3.7V input. A built-
in, 7-bit, digital soft-start function controls startup inrush
currents. The internally set output voltage is adjusted
through a unique communication protocol through the
single EN pin.
The IC is available in a 12-pin, 3mm x 3mm x 0.5mm,
ultra-thin DFN package with exposed pad and 0.5mm
lead spacing to facilitate placement on extremely narrow
circuit boards and a 24-pin, 4mm x 4mm, thin QFN pack-
age with exposed pad.
