General Description
The RY8310 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power
MOSFETs. It offers a very compact solution to provide a 1.2A continuous current over a wide input supply range,
with excellent load and line regulation.
The RY8310 requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package.
