General Description
The RY8406 devices are synchronous step-down DC/DC regulators. With an input range from 4V to 40V, they are
suitable for a wide range of applications, such as power conditioning from unregulated sources. They feature a low
RDSON (250mΩ/150mΩ typical) internal switch for maximum efficiency (90% typical). Support PSM mode (NonA Option) and Force-PWM mode (A option), Operating frequency is fixed at 2MHz, allowing the use of small
external components while still being able to have low output voltage ripple.
The RY8406 support 600mA Continuous Output Current, they all have a 0.6V nominal feedback voltage.
Additional features include: thermal shutdown, VIN undervoltage lockout, and gate drive undervoltage lockout. The
RY8406 are available in a low-profile SOT23-6 package.
