TPS65136

用于正负输出的单电感器多路输出 SIMO

The is designed to provide best-in-class picture quality for active-matrix OLED AMOLED displays that require positive and negative supply rails. With its wide input voltage range, the device is ideally suited for AMOLED displays, which are used in mobile phones or SmartPhone™ devices. With the new single-inductor multiple-output SIMO technology, the smallest possible solution size is achieved. The device operates with a buck-boost topology and generates both positive and negative output voltages above or below the input voltage rail. The SIMO technology enables excellent line and load regulation. Excellent line-transient regulation is required to avoid disturbance of the AMOLED display as a result of input voltage variations that occur during transmit periods in mobile communication systems.
