The EV2167B-D-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2167B, a configurable-frequency (300kHz to 2.2MHz), synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively). It provides up to 4A of continuous output current (I_OUT) with peak current control for excellent transient response.

The MPQ2167B can be configured for either advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM) at light loads. AAM mode provides high efficiency by reducing switching losses at light loads, while FCCM has a controllable frequency and lower output ripple.

The EV2167B-D-00A is a fully assembled and tested evaluation board. It generates 1.8V of output voltage (V_OUT) at load currents up to 4A from a 2.7V to 6V input voltage (V_IN) range with a 1.9MHz switching frequency (f_SW).
