TPS63805YFFR Description

The TPS63805, TPS63806, and TPS63807 are high efficiency, high output current buck-boost converters. Depending on the input voltage, they automatically operate in boost, buck, or in a novel 4-cycle buck-boost mode when the input voltage is approximately equal to the output voltage.

TPS63805YFFR Features

• Optimized for the smallest solution size of 18.5 mm2 (works with a 22-μF minimum output capacitor)

• 2-A output current for VI ≥ 2.3 V, VO = 3.3 V

• 11-μA operating quiescent current

TPS63805YFFR Applications

• System pre-regulator (smartphone, tablet, left terminal, and telematics)

• Point-of-load regulation (wired sensor, port/cable adapter, and dongle)
