Introduction

AI Translation

TPS6209x 器件是一款高效同步降压转换器，针对小外形尺寸、高效应用进行了优化，适合电池供电类应用。为最大限度提升效率，此转换器在 2.8 MHz/1.4 MHz 标称开关频率下以 PWM 模式运行，并在轻负载时自动进入省电运行模式。当用于分布式电源和负载点调制时，此器件允许对其它电源轨进行电压跟踪，并可耐受 10 μF 至高达 150 μF 甚至更高的输出电容。通过使用 DCS™ 控制技术，此器件可实现出色的负载静态性能以及精确的输出电压调制。 输出电压启动斜坡由软启动引脚控制，使器件可作为独立电源运行或运行于跟踪配置下。通过配置使能和开漏电源正常引脚，也可实现电源排序。在省电模式下，此器件以典型值 20 μA 的静态电流运行。在全部负载电流范围内，自动进入省电模式并无缝保持高效。

The TPS6209x synchronous switched mode converters are based on DCS™ Control (Direct Control with Seamless transition into Power Save Mode). This is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control. The DCS™ Control topology operates in PWM (Pulse Width Modulation) mode for medium to heavy load conditions and in Power Save Mode at light load currents. In PWM, the converter operates with its nominal switching frequency of 2.8 MHz/1.4 MHz having a controlled frequency variation over the input voltage range. As the load current decreases, the converter enters Power Save Mode, reducing the switching frequency and minimizing the IC quiescent current to achieve high efficiency over the entire load current range. DCS™Control supports both operation modes (PWM and PFM) using a single building block having a seamless transition from PWM to Power Save Mode without effects on the output voltage. Fixed output voltage versions provide smallest solution size combined with lowest quiescent current. The TPS6209x family offers excellent DC voltage regulation and load transient regulation, combined with low output voltage ripple, minimizing interference with RF circuits.
