The HT6605 is a fixed frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. It offers a very compact solution to achieve 5A continuous output current over a wide input supply range with excellent load and line regulation. The HT6605 has synchronous mode operation for higher efficiency over curent load range. Current mode operation provides fast transient response and eases loop stabilization.

The HT6605 has configurable line drop compensation,Full protection features include current limit. short circuit and thermal protection,The adiustable soft-start function prevents inrush current at turn-on.The HT6605 requires a minimum number of readily available standard extemal components and is available in a space saving SOP-8L package.
