Output currents can go as high as 1.5A in • 2.3V to 5.5V input voltage range boost mode and as high as 3A in buck mode. The maximum average current in the switches is limited to • 1.5A Continuous Output Current : VIN≥ 2.5V, a typical value of 3A. The TPS63024 regulates the VOUT= 3.3V output voltage over the complete input voltage range • Adjustable and fixed output voltage by automatically switching between buck or boost • Efficiency up to 95% in Buck or Boost mode and mode depending on the input voltage ensuring a up to 97% when VIN=VOUT seamless transition between modes. The buck-boost converter is based on a fixed frequency, pulse-width- • 2.5MHz typical switching frequency modulation (PWM) controller using synchronous • 35 μA operating quiescent current rectification to obtain highest efficiency. At low load • Integrated Soft –Start currents, the converter enters Power Save Mode to • Power Save Mode maintain high efficiency over the complete load current range. There is a PFM/PWM pin that allows • True shutdown function the user to choose between automatic PFM/PWM • Output capacitor discharge function mode operation and forced PWM operation. During • Over-Temperature Protection and Over current PWM mode a fixed-frequency of typically 2.5MHz is Protection used. The output voltage is programmable using an external resistor divider, or is fixed internally on the • Wide capacitance selection chip. The converter can be disabled to minimize • Small 1.766 mm x 2.086mm, 20-pin WCSP battery drain. During shutdown, the load is disconnected from the battery. The device is 2 Applications packaged in a 20-pin WCSP package measuring 1.766 mm x 2.086mm. • Cellular Phones, Smart Phones • Tablets PC Device Information(1) • PC and Smart Phone accessories PART NUMBER PACKAGE BODY SIZE (NOM) • Point of load regulation TPS63024 • Battery Powered Applications TPS630241 DSBGA (20) 1.766 mm × 2.086 mm TPS630242 (1) For all available packages, see the orderable addendum at the end of the datasheet. 4 Typical Application .
