8 Detailed Description
8.1 Overview
The TPS562200 and TPS563200 are 2-A and 3-A synchronous step-down converters. The proprietary D-
CAP2™mode control supports low ESR output capacitors such as specialty polymer capacitors and multi-layer
ceramic capacitors without complex external compensation circuits. The fast transient response of D-CAP2™
mode control can reduce the output capacitance required to meet a specific level of performance.
