The TPS65137 is designed to provide best in class picture quality for AMOLED displays
(Active Matrix Organic Light Emitting Diode) requiring positive and negative voltage supply rails.
With its wide input voltage range the device is ideally suited for AMOLED displays, which are used
in mobile phones and smart phones. With this device the input voltage can be higher than the
positive output voltage and still maintains accurate regulation of VPOS.
Using the digital control pin (CTRL) allows adjusting the negative output voltage in digital steps.
The TPS65137 uses a novel technology enabling excellent line and load regulation with minimum
output voltage ripple by using a LDO post regulator for VPOS. This is
required avoiding disturbance of the AMOLED display due to input voltage transients occurring
during transmit periods in mobile phones.
