Product Description

The EVQ4480-V-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4480, which 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, ground short to battery protection and thermal shutdown (TSD).

The MPQ4480 requires a minimum number of readily available, standard, external components. The MPQ4480 is available in a QFN25 (4mmx5mm) package
