1 Introduction

The TPS54JB20 is a D-CAP3™ synchronous buck converter, designed for 20-A output current, and evaluation module are designed to demonstrate the small printed-circuit-board areas that can 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 1-1.
