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 RY8411 supports 1.2A continuous output current, and it has a 0.8V nominal feedback voltage. Additional features include: thermal shutdown, VIN undervoltage lockout, and gate drive undervoltage lockout. The RY8411 is available in a low-profile SOT23-6 package.
