MPQ73351FS-AEC1

MPSafe^TM ASIL-D, 40V, High Output Current, Synchronous, Dual Buck Converter, AEC-Q100 Qualified

详情

The MPQ73351FS-AEC1 is an ASIL-D, high output current (I_OUT), synchronous, dual buck converter designed for automotive safety applications. It has a wide input voltage (V_IN) range, fast transient response, high efficiency, rich monitoring and protection features, and good EMI performance.

The device can be selected to operate in either 2-channel mode or single-output multi-phase mode. For 2-channel mode, I_OUT for each buck is up to 7A with the capability for 12A with a heatsink. Multiple MPQ73351FS-AEC1 chips in parallel can also support four-phase or eight-phase modes.

The switching frequency (f_SW) is configurable from 200kHz to 2.2MHz, or it can be synchronized with an external clock signal. Frequency spread spectrum (FSS) is featured to improve EMI performance.

Comprehensive protection features include input under-voltage lockout (UVLO), input over-voltage protection (OVP), cycle-by-cycle peak current limiting, output OVP, output short-circuit protection (SCP), and thermal shutdown. Different configurations can easily be configured via the selectable SPI or I²C interface. The one-time programmable (OTP) memory allows for vast flexibility through programmability.

The MPQ73351FS-AEC1 is available in a TQFN-28 (5mmx6mm) package, and is available in AEC-Q100 Grade 1.
