SLVSBJ9B – MAY 2014 – REVISED MARCH 2015 TPS63025x High Current, High Efficiency Single Inductor Buck-Boost Converter
1 Features 3 Description The TPS63025x are high efficiency, low quiescent
current buck-boost converters suitable for application
where the input voltage is higher or lower than the
output. Output currents can go as high as 2 A in
boost mode and as high as 4 A in buck mode. The
maximum average current in the switches is limited to
a typical value of 4 A. The TPS63025x regulates the
output voltage over the complete input voltage range
by automatically switching between buck or boost
mode depending on the input voltage ensuring a
seamless transition between modes. The buck-boost
converter is based on a fixed frequency, pulse-widthmodulation (PWM) controller using synchronous
rectification to obtain highest efficiency. At low load
currents, the converter enters Power Save Mode to
maintain high efficiency over the complete load …
