The EVQ2177F-QH-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2177FGQHE-AEC1, a monolithic, step-down switch-mode converter with built-in internal power MOSFETs.

The MPQ2177F-AEC1 achieves up to 1A of output current (I_OUT) across a 2.5V to 6V input voltage (V_IN) range, with excellent load and line regulation. The output voltage (V_OUT) can be regulated to as low as 0.6V. When V_IN > 3V, a 100% maximum duty cycle can be reached in dropout.

Constant on-time (COT) control offers a simpler control loop and faster transient response. By using V_IN feed-forward, the MPQ2177F-AEC1 maintains a nearly constant switching frequency (f_SW) across the entire input and load ranges.

Advanced asynchronous modulation (AAM) mode provides high efficiency by reducing switching losses at light loads.

An open-drain power good (PG) signal indicates the nominal voltage after the soft-start time (t_SS). PG pulls high once the feedback voltage (V_FB) reaches 95.5% of the reference voltage (V_REF), and is pulled to GND when V_FB drops to 90% of V_REF.

Full protection features include cycle-by-cycle current limiting, short-circuit protection (SCP), over-voltage protection (OVP), and thermal protection with auto-recovery.

The EVQ2177F-QH-00A is a fully assembled and tested evaluation board. The MPQ2177F-AEC1 is available in a QFN-8 (1.5mmx2mm) package, and it is AEC-Q100 qualified.
