The TPS63051YFFT is a high-efficiency buck-boost converter designed for applications requiring seamless voltage regulation when the input voltage is either above or below the output voltage. It operates within an input voltage range of 2.5 V to 5.5 V and can deliver a continuous output current of up to 500 mA in boost mode and 1 A in buck mode. The device features a fixed output voltage of 3.3 V and utilizes synchronous rectification to achieve efficiencies greater than 90% in boost mode and over 95% in buck mode. This converter employs a fixed-frequency pulse-width modulation (PWM) controller with a typical switching frequency of 2.5 MHz, and it can automatically switch between power save mode and forced PWM mode to optimize efficiency across varying load conditions. The TPS63051YFFT is packaged in a compact 12-pin DSBGA format, making it suitable for space-constrained applications such as smartphones, tablets, and battery-powered devices. It also includes features like adjustable soft-start time, overtemperature protection, and load disconnect during shutdown to minimize battery drain.
