一.产品概述
CXSD6235 CXSD6235A CXSD6235B是一款耐压6V,输出电流达3A的同步降压转换器。CXSD6235提供了频率调整引脚,可以让客户根据系统(特别是通讯系统)需求,调整此芯片的开关频率以避开系统的工作频率,防止干扰。同时CXSD6235提供三种不同的子型号,CXSD6235是3.6V启动工作,纯PWM工作模式,专为3G模块和机顶盒应用准备;CXSD6235A是2.5V启动工作,纯PWM工作模式;CXSD6235B是2.5V启动工作,PWM/PFM自动切换工作模式,有轻载高效功能,适用于平板电脑等电池供电产品。
The CXSD6235A is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 3A of output current. The device operates from an input voltage range of 2.6V to 5.5V and provides an output voltage from 0.8V to VIN, making the CXSD6235A ideal for low voltage power conversions. External programmable frequency and compensation network of the CXSD6235A enable system designers to make trade off according to different requirements such as board space, output transient response and efficiency. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability. CXSD6235A is housed in a DFN-10 Package
