RY8401 - RYCHIP

RY8401 Standoff 42V 0.6A 800KHz Sync Step-Down Regulator

The RY8401 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 (500mΩ/300mΩ typical) internal switch for maximum efficiency (92% typical). Supports PSM mode, the operating frequency is fixed at.
