TPS564208 Step-Down Voltage Regulator IC Chip

TPS564208（4.5-V to 17-V Input, 4-A Synchronous Step-Down Voltage Regulator in SOT-23）

Introduction

The TPS564208 is a simple,easy-to-use, 4-A synchronous step-down converter in SOT-23 package. The device is optimized to operate with minimum external component count and also optimized to achieve low standby current.

These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a fast transient response and supporting both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.

The TPS564208 is available in a 6-pin 1.6-mm x 2.9mm SOT (DDC) package, and specified from a -40°C to 125°C junction temperature.
