Maxim IC MAX17116 Dual-Output DC/DC Power Supply for AMOLED

Maxim Integrated MAX17116 Dual-Output
DC/DC Power Supply for AMOLED

Maxim Integrated MAX17116 Dual-Output DC/DC Power Supply ICs feature best-in-class efficiency and accuracy for improved image quality and battery lifetime in active-matrix organic LED (AMOLED) displays. Maxim Integrated's MAX17116 power supply devices include two current-mode 1.4MHz switch mode power-supply (SMPS) regulators. 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™. Its 4.6V (fixed) output efficiency exceeds 85% at 150mA from a 3.7V input. 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. These MAX17116 Dual-Output DC/DC Power Supply ICs for AMOLED are optimized for use in OLED displays as well as phone/DSC displays, and automobile navigation applications.
