TPS630252 features: input voltage range 2.3V to 5.5V; adjustable and fixed output voltage; 2.5MHz typical switching frequency; running quiescent current 35μA
TPS630252 typical application range: mobile phones, smart phones; tablet PCs; battery-powered applications
TPS630252 reference design application circuit:
Figure 1 TPS630252 internal structure diagram
TPS630252 Single Inductor Buck-Boost Converters are high efficiency, low quiescent current converters suitable for applications where the input voltage is higher or lower than the output. Output currents can go as high as 2A in boost mode and as high as 4A in buck mode.
Figure 2 TPS630252 reference design
The maximum average current in the switches is limited to a typical value of 4A. The TPS630252 regulates the output voltage over the complete input voltage range by automatically switching between buck or boost mode.
