MPQ71020FS-AEC1

MPSafe^TM, ASIL-D, 6V, 30A, Synchronous Buck Converter with ZDP^TM, AEC-Q100 Qualified

概要

The MPQ71020FS-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 MPQ71020FS-AEC1 operates from a 2.7V to 6V input voltage (V_IN) range and provides 30A of highly efficient output current (I_OUT) with fixed-frequency, zero-delay PWM (ZDP^TM) control for fast transient response.

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

High power conversion efficiency across a wide load range is achieved by skipping pulses under light-load conditions to reduce the f_SW 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. These protections provide reliable, fault-tolerant operation.

The MPQ71020FS-AEC1 integrates an I²C digital interface with packet error checking (PEC) and integrated, multi-page one-time programmable (OTP) memory, which allows for programming by the user with a high degree of configurability.

With the integration of functional safety features such as the 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. It is developed under MPS's advanced MPSafe^TM Functional Safety Product Development process, which has been independently certified to meet ISO 26262 guidelines.

The MPQ71020FS-AEC1 is available in a TLGA25 (3mmx4.5mm) package, and it is available in AEC-Q100 Grade 1.
