TPS630241 - Texas Instruments

TPS630241 High Efficiency Single Inductor Buck-Boost Converter

The TPS63024 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 1.5A in boost mode and as high as 3A in buck mode. The maximum average current in the switches is limited to a typical value of 3A. The TPS63024 regulates the outp.
