MPQ28261 21V, 3A, 500kHz Synchronous Step-Down Converter DESCRIPTION The MPQ28261 is a synchronous, rectified, step-down, switch-mode converter with built-in 120mΩ high-side MOSFET and 20mΩ low-side MOSFET. It offers a very pact 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...
