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 (250m?/150m? 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設備是高效、同步降壓直流/直流調(diào)節(jié)器。它具有廣泛的輸入范圍，適用于廣泛的應用，如來自不受調(diào)節(jié)的源的功率調(diào)節(jié)。它具有低RDSON (250mΩ/150mΩ典型）內(nèi)部開關，以實現(xiàn)最大效率(92%典型）。支持PSM模式，工作頻率固定在800 kHz，允許使用小的外部組件，同時仍然能夠具有較低的輸出電壓紋波。通過OVP功能，集成電路可以抵抗高達42V的輸入電壓。RY8413支持1.2A的連續(xù)輸出電流，并且它具有一個0.765V的標稱反饋電壓。
其他功能包括：熱關閉、VIN欠電壓鎖定，和柵極驅動欠電壓鎖定。RY8413有一個低調(diào)的SOT23-6封裝。
