2 Introduction

TPS51396A DC/DC converter is a synchronous buck converter designed to provide up to a 8-A output. The input (VIN) is rated for 4.5 V to 24 V. The TPS51396A uses a proprietary DCAP3 Control mode. Rated input voltage and output current range for the evaluation module are given in Table 2-1. The high-side and low-side MOSFETs are incorporated inside the TPS51396A package along with the gate-drive circuitry. An external divider allows for an adjustable output voltage. Additionally, the TPS51396A provides 1.3ms internal soft start or external soft start, under voltage lockout inputs and power good output.
