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 (VIN) range. The device provides up to 8A of highly efficient output current (IOUT) with fixed-frequency and employs zero-delay pulse-width modulation (PWM) (ZDPTM) control, an MPS-exclusive technology that enables near optimal transient response. The configurable 2MHz to 4MHz switching frequency (fSW) during forced continuous conduction mode (FCCM) reduces the external inductance (L) and capacitance (COUT). 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 fSW 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.
