Overview
MAX17116 19-5653; Rev 0; 12/10 EVAALVUAAILTAIOBNLEKIT 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 85% at 150mA from a 3.
7V input.
A built-in, 7-bit, digital soft-start function 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 efficiency exceeds 80% at 150mA from a 3.
7V input.
A builtin, 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 package with exposed pad.
