DESCRIPTION
The TPS65135 is a high efficient single inductor dual output converter. Due to its single-inductor multiple-output
(SIMO) technology the converter uses a minimum of external components. The device operates with a buck-
boost topology and generates a positive and a negative output voltage above or below the input voltage rail. The
SIMO technology enables excellent line and load regulation which is for instance required 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 standard ± supply as long as the output current
mismatch between the rails is smaller than 50%.
