PRODUCTION DATA.
The TPS63810 and TPS63811 devices are high-efficiency buck-boost converters. Each device uses four switches to maintain synchronous power conversion under all operating conditions, so that the device achieves high efficiency power conversion over a wide range of input voltages and output currents. The device automatically switches between buck, boost, and buck-boost operation as required by the operating conditions. The device operates as a true buck converter when VI > VO and as a true boost converter when VI < VO. When VI ≈ VO, the device operates in a 4-cycle buck-boost mode. The RMS current through the switches and the inductor is thus kept to a minimum, minimizing switching and conduction losses. Controlling the switches this way lets the converter achieve high efficiency over the whole input voltage range.
