The EVQ2176-RA-6003-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2176-6003-AEC1, a monolithic, step-down switch-mode converter with built-in, internal power MOSFETs.

The MPQ2176-6003-AEC1 achieves up to 6A of output current (I_OUT) across a 2.4V to 5.5V input voltage (V_IN) range, with excellent load and line regulation. The output voltage (V_OUT) can be regulated to as low as 0.4V.

The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. By using V_IN feed-forward, the MPQ2176-6003-AEC1 maintains a nearly constant switching frequency (f_SW) across the entire input and load ranges. Forced continuous conduction mode (FCCM) offers a stable frequency and a lower V_OUT ripple.

An open-drain power good (PG) signal indicates the nominal voltage after the soft-start time (t_SS) elapses. If the feedback voltage (V_FB) is within 96% to 105% of V_REF, then PG is pulled high by the external voltage source. If V_FB exceeds 112% or drops below 90% of the reference voltage (V_REF), then the PG voltage (V_PG) is pulled to GND to indicate an output failure.

Fault protections include cycle-by-cycle current limiting, input and output over-voltage protection (OVP), and thermal shutdown.

The EVQ2176-RA-6003-00A is a fully assembled and tested evaluation board. The MPQ2176-6003-AEC1 is available in a small QFN-7 (1.5x2.5mm) package with wettable flanks, and is AEC-Q100 qualified.
