The CXSD6233 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 1.5A/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 CXSD6233 ideal for low voltage power conversions. Running at a fixed frequency of 3MHz 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 thermaloverload protection improves design reliability

一.产品概述
CXSD6233是一款耐压6V，输出电流高达2A的同步降压转换器。CXSD6233工作的开关频率达到3MHz，领先国内众多竞争对手，允许使用超小的1uH电感，并使得输出纹波小至10mV。1uH的电感的内阻和体积更小，使得使用了CXSD6233后，降低电感损耗，提高能量转换效率的同时，系统的整机占板面积更小。同时CXSD6233在输出轻载时，进入调频模式，维持了轻载时的高转换效率。
