The MPQ3447-AEC1 is a high-efficiency, current-mode, synchronous boost controller with a 6V to 80V wide input voltage (V_IN) range. It can operate at multiple phases for high power applications. The device also has the capability to drive 10V MOSFETs, greatly improving efficiency and minimizing power loss.

It provides either an I²C (default) or SPI interface to configure some key operating parameters, such as the switching frequency (f_SW), current limit, light-load mode, frequency spread spectrum (FSS), dead time (DT), soft-start (SS) time (t_SS), slope compensation, etc. f_SW can be adjusted from 250kHz to 2.5MHz or synchronized directly to the external source.

The device also includes under-voltage lockout (UVLO), current limit, and thermal shutdown protection.

The MPQ3447-AEC1 is available in a QFN-21 (5mmx5mm) package. It is available in AEC-Q100 Grade 1.
