DESCRIPTION The MPQ4480 is a high-frequency, synchronous rectified, step-down, switch-mode converter. It achieves 6A output current over a wide input-supply range with excellent load and line regulation over a wide input supply range. The MPQ4480 has synchronous mode operation for higher efficiency over the output load range. Fault condition protection includes hiccup current limiting, OVP, and thermal shutdown (TSD). The MPQ4480 requires a minimal number of readily available, standard external components. The MPQ4480 is available in a QFN-25 (4mmx5mm) package.
