MPQ2241 - Configurable-Frequency Synchronous Buck Converter

General Description

The MPQ2241 is a configurable-frequency (300kHz to 2.2MHz), synchronous, step-down converter.

It can achieve up to 1A of continuous output current (IOUT) with peak current control for excellent transient response and efficiency.

Key Features

  • including soft start (SS), enable (EN) control, and power good (PG) indication. In addition, the MPQ2241 provides over-current protection (OCP) with valley current detection to avoid current runaway, short-circuit protection (SCP), reliable over-voltage protection (OVP), and autorecovery thermal protection. With internal compensation, the MPQ2241 requires a minimal number of readily available, standard external components. It is available in a QFN-9 (2mmx3mm) package, and is AECQ100 qualified.

DESCRIPTION The MPQ2241 is a configurable-frequency (300kHz to 2.2MHz), synchronous, step-down converter. It can achieve up to 1A of continuous output current (IOUT) with peak current control for excellent transient response and efficiency. The MPQ2241 operates from a 2.7V to 6V input voltage (VIN) range and generates an output voltage (VOUT) 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 integrates a 35mΩ high-side MOSFET (HS-FET) and a 25mΩ synchronous rectifier for high efficiency without an external Schottky diode. The MPQ2241 can be configured for either advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM) at light loads.
