RY9330 - RYCHIP

RY9330 28V 3A 500KHz ECOT PSM Sync Step-Down Regulator

The RY9330 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to provide a 3A continuous output current over a wide input supply range, with excellent load and line regulation. ECOT PSM control operation provides very fast transient response and easy loop design as wel.
