1 Introduction

The TPS563211 is a single, Advanced Emulated Current Mode (AECM) control, synchronous Buck converter, being able to deliver 3-A continuous output current, providing selectable Eco-mode operation or FCCM operation and selectable Power-Good indicator or external Soft-Start by the configuration of the MODE pin. Power sequencing is possible by correctly configuring the Enable, Power-Good indicator or external Soft-Start. The device implements an AECM control which can get fast transient response with fixed frequency. The fast transient response results in low voltage drop and the fixed frequency brings a better jitter permanence and predictable frequency for EMI design. The optimized internal compensation network minimizes the external component counts and simplifies the control loop design over a wide voltage output range. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.

The TPS563211EVM is a single, synchronous buck converter providing 3.3 V at 3 A from 4.2-V to 18-V input. This user’s guide describes the TPS563211EVM performance.
