RP504X是一种低电源电流的基于CMOS的脉宽调制（PWM/VFM）降压型DC/DC变换器，同步整流器具有600 mA*1的输出电流。在内部，一个转换器由一个振荡器、一个参考电压单元、一个误差放大器、一个开关控制电路、一个模式控制电路（rp504xx1a/d）、一个软启动电路、一个锁存式保护电路、一个欠压锁定（uvlo）电路和一个开关晶体管组成；rp504x采用同步整流的方式来实现。用内置开关晶体管代替二极管，提高整流效率。采用同步整流不仅提高了电路性能，而且使设计减少了部件数量；功率控制方式可从强制PWM控制方式或PWM/VFM自动切换控制方式中选择，通过向模式引脚输入信号。在低输出电流下，强制脉宽调制控制开关以固定的频率率来降低噪声。同样，在低输出电流下，PWM/VFM自动切换控制自动从PWM模式切换到VFM模式，以实现高效率；输出电压为内部固定型，允许输出电压在0.1 V步进范围从0.8 V到3.3 V。
输出电压精度高达±1.5%或±18mV；RP504X中的保护电路为过流保护电路和闭锁式保护电路。
过流保护电路监控每个开关周期中的感应器峰值电流，如果电流超过lx电流限制（ILXLIM），它将关闭P通道Tr。闭锁式保护电路将内置驱动器锁定到关闭状态，如果过流状态持续或在等于或大于保护延迟时间（tprot）的情况下，Vout继续是设定电压的一半。要取消闭锁式保护电路，请使用CE引脚选择待机模式或激活模式，或将电源电压降低到uvlo检测器阈值以下；RP504X提供6针DFN（PLP）1216-6F、6针DFN1616-6B和5针SOT-23-5封装，在面积为LI的电路板上实现最小可能的封装解决方案。被钉住的；
*1这是一个近似值。输出电流取决于条件和外部元件。
