General Description
The RY8413 devices are high-efficiency, synchronous step-down DC/DC regulators. With a wide input range, 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 (92% typical). Support PSM mode
(Non-A Option) and Force-PWM mode (A option), 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 45V. The RY8413 support 1.2AContinuous Output Current, they all have a 0.765V
nominal feedback voltage.
Additional features include: thermal shutdown, VIN undervoltage lockout, and gate drive undervoltage lockout. The
RY8413 are available in a low-profile SOT23-6 package.
