G5676

Global Mixed-mode Technology G5676 5A Synchronous Step-Down DC/DC Features 5A Output Current* 75mΩ Internal Power MOSFET Switch Stable with Low ESR Output Ceramic Capacitors or POSCAPs Less Than 1µA Shutdown Current 1MHz Switching Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Output Adjustable from 0.6V to VIN Available in SOP-8 (FD) Package *The output voltage should be less then 1.8V. If the Vout setting is larger then 1.8V, the output current will be less then 5A because of thermal protection. Applications NB Distributed Power Systems Pre-Regulator for Linear Regulators General Description The G5676 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves a continuous output current at 1MHz switching frequency with excellent load and line regulation. Current mode operation provides fast transient response and eases of loop stabilization. Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator ground current is controlled less than 1µA. An Internal soft-start minimizes the inrush supply current at initial startup. The G5676 requires a minimum number of readily available standard external components. It is available in SOP-8 (FD) package. Ordering Information ORDER NUMBER G5676F11U Note: F1: SOP-8 (FD) 1 : Bonding Code U : Tape & Reel Pin Configuration MARKING G5676 TEMP.
