1 Introduction

The TPS53211 1.5-V to 19-V, single phase PWM buck controller with light load efficiency provides the control of a high-efficiency switch-mode buck voltage regulator. The TPS53211 uses external enhancement mode N-channel MOSFET switches to convert the input voltage to a regulated output voltage. In this applications note, we will review TI's guidelines and recommendations for selection of the MOSFETs for use with the TPS53211. Following these guidelines will simplify the design process and provide cost effective, efficient conversion while avoiding potential design issues that can be associated with inappropriate MOSFET selections.
