AME AME5285 5A, 300KHz ~ 1.4MHz Synchronous Rectified Step-Down Converter n General Description The AME5285 is a Synchronous Rectified Step-Down Converter with internal power MOSFETs. It achieves 5A continous output current over a wide switching frequency range with excellent load and line regulation. Current mode operation provides fast transient response and eases of loop stabilization. Internal soft-start minimizes the inrush supply current at startup. The circuit protection includes cycle-by cycle current limiting, output short circuit frequency protection and thermal shutdown. This device is available in SOP-8/PP package with exposed pad for low thermal resistance.
