CXSD6231是一款耐压7V，输出电流达1.2A的同步降压转换器。其1.5MHz的开关频率，可以使用2.2uH的电感，甚至在小电流是可以使用物美价廉的叠层电感。CXSD6231以其极高的能量转换效率、超低的静态功耗和较大的输出电流，可广泛应用与机顶盒，LCDTV，平板电脑能几乎所有用电设备。同时其高达7V的耐压可以用于4节干电池供电的如玩具等电子系统</span>
The CXSD6231 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 1.2A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide output voltages from 0.6V to VIN, making the CXSD6231 ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies. Other external components, such as ceramic input and output caps, can also be small due to higher switching frequency, while maintaining exceptional low noise output voltages. Built-in EMI reduction circuitry makes this converter ideal power supply for RF applications. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability. CXSD6231 is housed in a tiny SOT23-5L package
