【产品】 1A PWM/VFM 双路降压型DC/DC转换器RP550K001A,待机电流最大仅10μA
NISSHINBO (日清纺)RP550K001A是一款基于CMOS的带有同步整流器的1A*1双路降压DC/DC转换器。 其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、软启动电路、锁存型保护电路、欠压锁定(UVLO)电路、热关断电路和开关晶体管组成。RP550K001A用内置开关晶体管代替二极管可提高整流效率。因此,通过简单地使用两个电感器、电阻器和电容器作为外部元件,就可以方便地配置低纹波、高效率同步整流器降压型DC / DC转换器。
RP550K001A双路降压DC/DC转换器的锁存型保护电路在高负载或输出在指定时间(保护延迟时间)短路时,会将内置驱动器锁存到OFF状态。如果使用CE引脚将转换器设置为待机模式,然后将其设置回激活模式,又或者是通过关闭电源并重新打开,两种方式都可以释放锁存保护电路。另外,将电源电压设置为低于UVLO检测器阈值也可以释放锁存保护电路。热关断电路用于检测转换器是否过热,若过热则停止转换器操作,以防止结温超过指定温度时损坏转换器。通过向MODE引脚输入信号,RP550K001A可以选择PWM / VFM自动切换控制或强制PWM控制。在低输出电流时,PWM / VFM自动切换控制自动从PWM模式切换到VFM模式,以实现高效率运行。同样,在低输出电流时,强制PWM控制以固定频率切换可以降低噪声。当两个转换器都处于PWM控制状态时,转换器在开关晶体管的180°导通相移下工作。

Nisshinbo R5661 Series 1-Cell Li-ion Battery Protection IC with Temperature Protection
The R5661 is one-cell Li-ion / polymer battery protection IC provides overcharge, overdischarge, discharge / charge overcurrent, and temperature detections. One of the features of this device is a high-accuracy detection at overcharge and overcurrent. The supply current after overdischarge detection can be reduced to a minimum by stopping the internal circuits. The small WLCSP package is available.
