Texas Instruments has introduced an organic light emitting diode (OLED) power driver designed to enhance image quality for small form factor displays up to 2,5 inches.
The TPS65136 power IC supports active matrix OLED (AMOLED) displays used in mobile phones, digital cameras and portable media players.
AMOLED displays allow each pixel to emit its own light, resulting in high colour saturation, thin form factor, high contrast ratio, fast response time and low power consumption. The TPS65136 manages power to AMOLED displays by providing positive and negative voltages, and supplying less current and lower voltages than passive matrix displays.
With just one 2,2 μH inductor to generate both outputs on the single-inductor, multiple-output converter technology, the device provides high picture quality and achieves a small solution size with a low component count. A buck-boost topology allows the device to generate a positive voltage up to 4,6 V and adjustable negative output voltage down to -7 V. In addition, the input voltage can be above or below the positive output voltage, allowing it to support new batteries with a starting voltage up to 4,8 V.
The unique converter technology results in excellent line and load regulation, which is required to avoid potential display disturbances in mobile devices during transmit periods. The converter also lowers the switching frequency as the load current decreases, to maintain high efficiency over the entire load current range. The TPS65136 maintains the switching frequency above the audible range with a voltage-controlled oscillator to avoid causing audible noise from the vibration of the ceramic output capacitors.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
