1 Introduction

The TPS548B27 is a D-CAP3? synchronous buck converter designed for 20-A output current, and the evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the device. The high-side and low-side switching MOSFETs are integrated in the device package along with their gate drive circuitry. Rated input voltage and output current ranges for the evaluation module are given in Table 3-1.
