1 Introduction

The TPS56x25x is a simple, easy-to-use, high efficiency, high power density, synchronous buck converter with input voltage ranging from 3 V to 17 V and supports output voltages between 0.6 V and 10 V. TPS56x25x uses small SOT563 package which is 1.6 mm × 1.6 mm and uses HotRod package technology. TPS56x25x has good thermal performance and loop stability. Table 1-1 shows the comparison table for TPS56x25x family parts. These parts can be widely used in Wi-Fi™ access point, switch, router, pro-audio, TV, STB and so on.
