The MPQ7931 is a power management IC (PMIC) designed to meet the power management requirements of processors used in various safety-relevant automotive systems.

Six integrated synchronous buck converters can be configured as 3 dual-phase or 6 single-phase converters. With dynamic voltage scaling, the output voltage (V_OUT) of each converter can be changed during normal operation. The serial interface provides packet error checking (PEC) and an integrated memory to allow a high degree of configurability.

Six enable pins allow each regulator to be sequenced independently for flexible timing control. This allows the device to meet a wide variety of sequencing requirements. To prevent overshoot during start-up, soft-start (SS) functionality is featured on each converter, and the slew rate can be configured.

A 2MHz, fixed-frequency pulse-width modulation (PWM) control regulates V_OUT, offers fast transient response performance, and significantly reduces external inductance and capacitance. Frequency spread spectrum (FSS) reduces EMI noise. The full protection suite includes under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown.

The MPQ7931 is available in a QFN-32 (5mmx5mm) package.
