TPS65135RTER

The TPS65135 device is a high-efficiency split-rail
power supply. Thanks to its single-inductor, multipleoutput (SIMO) topology, the converter uses very few
external components. The device operates with a
buck-boost topology and generates positive and
negative output voltages above or below the input
supply voltage. The SIMO topology achieves
excellent line and load regulation, which is necessary,
for example, to avoid disturbance of a mobile phone
display as a result of input voltage variations that
occur during transmit periods in mobile
communication systems. The device can also be
used as a general-purpose split-rail supply as long as
the output current mismatch between the rails is less
than 50%.
