资 源 简 介
The MAX17116 includes two current-mode 1.4MHz switch mode power-supply (SMPS) regulators for acTIvematrix
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 ShutdownTM.
Its 4.6V (fixed) output efficiency exceeds 85% at 150mA
from a 3.7V input. A built-in, 7-bit, digital soft-start function controls startup inrush currents.
