RT8251GQW Beschreibung
The RT8251GQW is a monolithic step-down switch mode converter with a built-in internal power MOSFET. It achieves 5A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization.The RT8251GQW provides protection functions such as cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the regulator draws 25μA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. The RT8251GQW requires a minimum number of external components. The RT8251GQW is available in WQFN-16L 3x3 and SOP-8 (Exposed Pad) packages.
