1 Introduction

TPS568230 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 18 V. The TPS568230 uses a proprietary DCAP3 Control mode. Rated input voltage and output current range for the evaluation module are given in Table 1-1. The high-side and low-side MOSFETs are incorporated inside the TPS568230 package along with the gate-drive circuitry. An external divider allows for an adjustable output voltage. Additionally, the TPS568230 provides 1.3ms internal soft start or external soft start, under voltage lockout inputs and a power good output.
