RY3820E

    The RY3820E is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to provide a 2A continuous current over a wide input supply range,with excellent load and line regulation.

    The RY3820E requires a minimal number of readily available, external components and is available in a space saving SOT23-6 package.
