Description
The MPQ4276A-AEC1 integrates a monolithic, step-down switch-mode converter with two USB current-limit switches, as well as USB Type-C 5V @ 3A mode configuration channels for each port. The MPQ4276A can achieve up to 6A of output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation.
The USB switch’s output is current-limited. Both USB ports support USB Type-C 5V @ 3A DFP mode, which eliminates the need for external user interaction. The MPQ4276A uses peak current mode control to regulate the output voltage (VOUT). Under light-load conditions, the device enters pulse-frequency modulation (PFM) mode to improve light-load efficiency.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown. The MPQ4276A requires a minimal number of readily available, standard external components, and is available in a QFN-26 (5mmx5mm) package.
