Controller IC Chip - MOSFET G5671RE1U G5671 5671 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0459)

3A Synchronous Step-Down DC/DC

The G5671 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves a continuous output current at 1MHz switch-ing frequency with excellent load and line regulation. Current mode operation provides fast transient re-sponse and eases of loop stabilization. Power good function delivers power supply ready signal to the load. Fault condition protection includes cycle-by-cycle cur-rent limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator ground current is controlled less than 1mA. An Internal soft-start minimizes the inrush supply current at initial startup. The G5671 requires a minimum number of readily available standard external components. It is available in TDFN3X3-10 package.
