EVQ2284-L-00A

The EVQ2284-L-00A evaluation board is designed to demonstrate the capabilities of the MPQ2284-AEC1, a configurable, high-frequency, synchronous buck converter with integrated internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively).

The MPQ2284-AEC1 operates from a 2.7V to 6V input voltage (V_IN) range. The device provides up to 8A of highly efficient output current (I_OUT) with fixed-frequency and employs zero-delay pulse-width modulation (PWM) (ZDP^TM) control, an MPS-exclusive technology that enables near optimal transient response.

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

High power conversion efficiency across the wide load range is achieved by scaling down f_SW under light-load conditions to reduce switching 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 enables a high degree of configurability.

The EVQ2284-L-00A is a fully assembled and tested evaluation board. The MPQ2284-AEC1 is available in a QFN-18 (3mmx4mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
