DESCRIPTION
The TPS65136 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.
