8.1 Overview

The TPS631010 and TPS631011 are constant frequency peak current mode control buck-boost converters. The converters use a fixed-frequency topology with approximately 2-MHz switching frequency. The modulation scheme has three clearly defined operation modes where the converters enter with defined thresholds over the full operation range of VIN and VOUT. The maximum output current is determined by the Q1 peak current limit, which is typically 3 A.
