RY8411 Standoff 42V 1.2A 800KHz Sync Step-Down Regulator
The RY8411 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 lowRDSON(250m?/150m? typical) internal switch for maximum efficiency (92% typical). Supports PSM mode, theoperating frequency is fixed at 800kHz, allowing the use of small external components while still being able to havelow output voltage ripple. With OVP function, the IC can stand off input voltage as high as 42V.
