1 Introduction

The TPS56339 is a single, Advanced Emulated Current Mode (AECM) control, synchronous Buck DC/DC converter, being able to deliver 3-A continuous output current, providing an advance Eco-mode to maintain high light load efficiency. The TPS56339 integrates 26-V capable MOSFETs which is suitable for applications working from 19-V bus power lines. 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.Table 1-1 shows the rated input voltage and output current ranges for the evaluation module.

The TPS56339EVM is a single, synchronous buck converter providing 5 V at 3 A from 5.5 V to 24 V input. This user’s guide describes the TPS56339EVM performance.
