DESCRIPTION
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.
