1 Introduction

The TPS56837 is an adaptive on-time D-CAP3™ control mode synchronous step-down DC/DC converter. With the wide operating input voltage range of 4.5 V to 28 V, the TPS56837 is designed for systems powered from 12-V, 19-V, 24-V power-bus rails. The device supports up to 8-A continuous output current between 0.6 V and 13 V. The TPS56837 device provides 500-kHz, 800-kHz and 1.2-MHz switching frequencies for selection. This switch mode power supply (SMPS) IC is optimized for applications requiring very low power consumption, such as printers, DTV, monitor and some industrial applications, by providing an Eco-mode™ (pulse-skipping). D-CAP3 control mode provides an easy-to-design, stable regulation with very little external components, and supports cost-effective ceramic capacitors. Table 1-1 shows the rated input voltage and output current ranges for the evaluation module.

The TPS56837EVM evaluation module (EVM) is a single, synchronous buck converter providing 5-V at 8-A output from 5.5-V to 28-V input. This user’s guide describes the TPS56837EVM performance.
