The MPQ71411FS-AEC1 is a configurable, high-frequency, ASIL-D, synchronous buck converter with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). The MPQ71411FS-AEC1 operates from a 2.7V to 6V input voltage (V_IN) and provides 30A of continuous (up to 40A peak), highly efficient output current (I_OUT) with fixed frequency, zero-delay pulse-width modulation (PWM) (ZDP^TM) control for fast transient response.

The configurable 2MHz to 4MHz configurable switching frequency (f_SW) during forced continuous conduction mode (FCCM) greatly reduces the external inductance and capacitance. Internal feedback and compensation minimizes external component count and improves accuracy.

High power conversion efficiency across a wide load range is achieved by skipping pulses under light-load conditions to reduce the switching frequency and gate driving losses. Full protection features include short-circuit protection (SCP), over-current protection (OCP), input over-voltage protection (OVP), output OVP, and thermal shutdown, which provide reliable, fault-tolerant operation.

The MPQ71411FS-AEC1 integrates an I²C digital interface with packet error checking (PEC) and multi-page one-time programmable (OTP) memory, which allows for user configurations with a high degree of configurability.

With integrated functional safety features such as logic built-in self-testing (LBIST) and analog built-in self-testing (ABIST), this ASIL-certified device supports applications with automotive safety integrity level ASIL-D. The device is developed under MPS's advanced MPSafe^TM functional safety product development process, which has been independently certified to meet ISO 26262 guidelines.

The MPQ71411FS-AEC1 is available in an TLGA-22 (3.5mmx5mm) package, and it is available in AEC-Q100 Grade 1.
