Dual-Output DC/DC Power Supply for AMOLED
General Description
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 8...
