RP508K Series 600 mA 6 MHz Synchronous Step-down DC/DC Converter
■大纲
●RP508K是一款低电源电流PWM/VFM降压DC/DC转换器，带有同步整流器，输出电流为600mA。在内部，单个转换器由振荡器、参考电压单元、误差放大器、开关控制电路、模式控制电路、软启动电路、欠压锁定（UVLO）电路、过电流保护电路、热关断电路和开关晶体管组成。
●RP508K采用内置开关晶体管的同步整流电路，作为高效的降压DC/DC转换器，无需连接外部二极管。使用同步整流不仅提高了电路性能，而且允许设计减少部件数量。
●通过向MODE引脚输入信号，可以从强制PWM控制类型或PWM/VFM自动切换控制类型中选择功率控制方法。在输出电流较低的情况下，强制PWM控制开关频率固定，以降低噪声。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0.1V步长内从0.8V到3.3V。输出电压精度高达±1.5%或±18mV。
●RP508K中包含的保护电路包括过电流保护电路和热关断电路。
●过电流保护电路在每个开关周期中监控电感器峰值电流，如果电流超过LX电流限制（ILXLIM），则关闭P通道Tr。如果输出引脚与接地引脚（GND）等短路，热关断电路会检测到转换器过热，如果接头温度超过规定温度，则会停止转换器操作以保护其免受损坏。
●RP508K采用小而薄的6引脚DFN（PL）1212-6F封装，在面积有限的板上实现了尽可能小的占地面积解决方案。
●对于输入电容器（CIN）和输出电容器（COUT），可以使用较小尺寸的0402/1005（英寸/mm）电容器。对于电感器（L），可以使用较小尺寸的0603/1608或1005/2012（英寸/mm）电感器。
