RY8413 Description/概述：
The RY8413 device is high-efficiency, synchronous step-down DC/DC regulators. With a wide input range, it is suitable for a wide range of applications, such as power conditioning from unregulated sources. It features a low RDSON (250mΩ/150mΩ typical) internal switch for maximum efficiency (92% typical). Supports PSM mode, the operating frequency is fixed at 800kHz, allowing the use of small external components while still being able to have low output voltage ripple. With OVP function, the IC can stand off input voltage as high as 42V. The RY8413 supports 1.2A continuous output current, and it has a 0.765V nominal feedback voltage.
Additional features include: thermal shutdown, VIN undervoltage lockout, and gate drive undervoltage lockout. The RY8413 is available in a low-profile SOT23-6 package.
RY8413设备是高效、同步降压直流/直流调节器。它具有广泛的输入范围，适用于广泛的应用，如来自不受调节的源的功率调节。它具有低RDSON (250mΩ/150mΩ典型）内部开关，以实现最大效率(92%典型）。支持PSM模式，工作频率固定在800 kHz，允许使用小的外部组件，同时仍然能够具有较低的输出电压纹波。通过OVP功能，bd体育登录入口app下载 可以抵抗高达42V的输入电压。RY8413支持1.2A的连续输出电流，并且它具有一个0.765V的标称反馈电压。
其他功能包括：热关闭、VIN欠电压锁定，和栅极驱动欠电压锁定。RY8413有一个低调的SOT23-6封装。
