1 Introduction

TPS566235 device is a high efficiency, cost effective, synchronous BUCK DC/DC converter with integrated FETs. It employs the proprietary D-CAP3™ control mode that is optimized for low-ESR output capacitors and features fast transient response without external compensation. The operating input voltage range is 4.5 V to 18 V, the output voltage can be programmed between 0.6 V and 7 V, and the output current is up to 6 A. The operating frequency is internally set to nominal 600 kHz in CCM, and there are 3 different operation modes can be configured by MODE pin at light load: Eco-Mode, Out-of-Audio, and FCCM. TPS566235 provides rich functions as well as excellent power supply performance, internal fixed 1mSec soft start, power good indicator, and full protections including UVLO, OCP, OVP, UVP, OTP. The devices are available in 3.0-mm × 2.0-mm HotRod™ package and the die operating temperature is specified from -40°C to 125°C.

TPS566235EVM-036 evaluation module (EVM) is designed for accessing to the features of TPS566235.
