MPQ2241-AEC1

6V, 1A, Configurable-Frequency, Synchronous Buck Converter, AEC-Q100 Qualified

Datasheet

Description

The MPQ2241-AEC1 is a configurable-frequency (300kHz to 2.2MHz), synchronous step-down converter. It can achieve up to 1A of continuous output current (I_OUT) with peak current control for excellent transient response and efficiency. The MPQ2241-AEC1 operates from 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, telematics, as well as portable instruments.

The MPQ2241-AEC1 integrates a 35mΩ high-side MOSFET (HS-FET) and a 25mΩ synchronous rectifier for high efficiency without an external Schottky diode.

The MPQ2241-AEC1 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 a lower output ripple.

The MPQ2241-AEC1 offers standard features, including soft start (SS), enable (EN) control, and power good (PG) indication. In addition, the MPQ2241-AEC1 provides over-current protection (OCP) with valley current detection to avoid current runaway, short-circuit protection (SCP), reliable over-voltage protection (OVP), and auto-recovery thermal protection.

With internal compensation, the MPQ2241-AEC1 requires a minimal number of readily available, standard external components. It is available in a QFN-9 (2mmx3mm) package, and it is available in AEC-Q100 Grade 1.

The EVQ2241-D-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2241-AEC1, a configurable-frequency (300kHz to 2.2MHz), synchronous step-down converter with an integrated high-side MOSFET (HS-FET) and a synchronous rectifier to provide high efficiency without an external Schottky diode.

The MPQ2241-AEC1 can achieve up to 1A of continuous output current (I_OUT), with an output voltage (V_OUT) down to 0.606V. It is ideal for a wide range of applications, including automotive infotainment systems, clusters, and telematics, as well as portable instruments.

Advanced asynchronous modulation (AAM) mode provides high efficiency by reducing switching losses at light loads, while forced continuous conduction mode (FCCM) has a controllable switching frequency (f_SW) and a lower V_OUT ripple. Peak current control mode provides excellent transient response and high efficiency.

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

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

The EVQ2241-D-00A is fully assembled and tested. The MPQ2241-AEC1 is available in a QFN-9 (2mmx3mm) package, and it is available in AEC-Q100 Grade 1.
