MPQ2283-AEC1

6V, 6A, Configurable, High-Frequency, Synchronous Buck Converter with ZDP^TM, AEC-Q100 Qualified

概要

The MPQ2283-AEC1 is a configurable, high-frequency, synchronous buck converter with integrated, internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). The MPQ2283-AEC1 operates from a 2.7V to 6V input voltage (V_IN) range and provides up to 6A of highly efficient output current (I_OUT) with fixed-frequency, zero-delay pulse-width modulation (PWM) (ZDP^TM) control for optimal transient response.

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

High power conversion efficiency across the wide load range is achieved by scaling down f_SW under light-load conditions to reduce 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 digital interface features packet error checking (PEC), and the integrated multi-page one-time programmable (OTP) memory allows for a high degree of configurability.

The MPQ2283-AEC1 is available in a QFN-18 (3mmx4mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
