MPQ4483
DESCRIPTION The MPQ4483 is a high-frequency, synchronous rectified, step-down, switch-mode converter. It achieves 3A output current over a wide input supply range with excellent load and line regulation. The MPQ4483 has synchronous mode operation for higher efficiency over the output load range. The MPQ4483 has a constant current (CC) limit function for the output with two adjustable CC limit thresholds. The MPQ4483 also supports BC 1.2 DCP mode and CDP mode. Fault condition protection includes hiccup current limiting, OVP, ground short to battery protection, and thermal shutdown (TSD). The MPQ4483 requires a minimum number of readily available, standard, external ponents. The MPQ4483 is available in a QFN25 (4mmx5mm) package.
