EVQ2246-Q-00A

The EVQ2246-Q-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2246-AEC1, a configurable-frequency (300kHz to 2.2MHz), synchronous step-down converter. The MPQ2246-AEC1 integrates a high-side MOSFET (HS-FET) and a synchronous rectifier to achieve high efficiency without an external Schottky diode.

The MPQ2246-AEC1 can support up to 6A of continuous output current (I_OUT) across a 2.7V to 6V input voltage (V_IN) range and generates an output voltage (V_OUT) as low as 0.606V. It is ideal for a wide range of applications, including automotive infotainment, clusters, and telematics, as well as portable instruments.

The MPQ2246-AEC1 can be configured for either advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM). AMM mode provides high efficiency by reducing switching losses at light loads, while FCCM has a controllable frequency and a lower output ripple. Peak current control mode provides excellent transient response and efficiency performance.

An open-drain power good (PG) signal indicates whether V_OUT is within 85% to 115% of its nominal voltage.

Full protection features include over-current protection (OCP) with valley current detection to avoid current runaway, short-circuit protection (SCP), reliable over-voltage protection (OVP), and thermal protection with auto-recovery.

The EVQ2246-Q-00A is fully assembled and tested. The MPQ2246-AEC1 is available in a QFN-9 (3mmx3mm) package, and is AEC-Q100 qualified.
