1 Introduction

The TPS542A50EVM-059 evaluation module (EVM) uses the Texas Instruments TPS542A50 buck converter. The TPS542A50 is a highly integrated high-efficiency synchronous buck converter with differential remote sensing and I²C. It is capable of delivering up to 15 A to a load with output voltages ranging from 0.5 V to 5.5 V. The high-side and low-side switching MOSFETs are integrated in the device package, along with their associated gate drive circuitry.

High efficiency, wide-operating junction temperature, and high output voltage accuracy make the TPS542A50 an excellent choice for applications where high output voltage accuracy across rigorous thermal conditions are required. The rated input voltage, output voltage, and output current range for the TPS542A50 are given in Table 1-1.
