About This Product

■Summary

The MPQ4276A-AEC1 also integrates a Type-C 5V@3A mode configuration channel for each port, as well as a monolithic step-down switch-mode converter and two USB current-limiting switches. The MPQ4276A provides up to 6A of output current (IOUT) over a wide input voltage (VIN) range with excellent load and line regulation. The USB switch output is current limited. Both USB ports support USB Type-C 5V@3A DFP mode, which requires no external user interaction. MPQ4276A uses peak current mode control to adjust the output voltage (VOUT). Under light load conditions, the device enters pulse frequency modulation (PFM) mode to improve light load efficiency. Extensive protection features include hiccup current limiting, output overvoltage protection (OVP), and thermal shutdown. The MPQ4276A requires a minimal number of off-the-shelf standard external components and is available in a QFN-26 (5mm x 5mm) package.

■Features and benefits

・Passed USB-IF Type-C certification test ・Passed Apple MFI certification exam - Automatic pulse frequency modulation (PFM) and pulse width modulation (PWM) modes Output enable when EN goes high or CC1, CC2, CC3, and CC4 are connected ・Control USB1 and USB2 on/off by setting EN1 and EN2 to active low. ・135℃ load shedding vs. temperature ・Accurate 5A USB1 and USB2 output current (IOUT) limit ・Wide operating input voltage (VIN) range from 6V to 36V ・Selectable output voltage (VOUT) ・Line drop compensation ・Low on-resistance (RDS (ON)) of 21mΩ and 15mΩ Internal power MOSFET for buck converter ・18mΩ and 18mΩ low RDS (ON) internal power MOSFETs for USB1 and USB2 ・Adjustable frequency from 200kHz to 2.2MHz Hiccup current limit for both buck converter and USB switch ・USB1 and USB2 failure display ・Supports USB Type-C 5V@3A mode
