The MPQ28261 is a synchronous, rectified, step-down, switch-mode converter with built-in 120mΩ high-side MOSFET and 20mΩ low-sideMOSFET. It offers a very compact solution to achieve a continuous 3A output current over a wide input supply range, with excellent load and line regulation. Its synchronous mode operation increases its efficiency over its output current load range, and uses a fixed 500kHz switching frequency.Current mode operation provides a fast transient response and improves loop stabilization. Full protection features include over-current protection and thermal shut down.The MPQ28261 has an external SS pin to program the soft-start time and power-good signal output.The MPQ28261 requires a minimal number of readily-available standard external components and is available in a space saving 3mmx4mm 14-pin QFN package.
