MPQ2167B-AEC1

6V, 4A, Configurable Frequency, Synchronous Buck Converter, AEC-Q100 Qualified

Datasheet

Description

The MPQ2167B is a synchronous step-down converter that achieves up to 4A of continuous output current with peak current control for excellent transient response and efficiency performance. The device operates from a 2.7V to 6.0V input range, generates an output voltage as low as 0.606V, and has a configurable frequency (300kHz to 2.2MHz). It is ideal for a wide range of applications, including automotive infotainment, clusters, telematics, and portable instruments.

The device integrates a 35mΩ high-side MOSFET and a 25mΩ synchronous rectifier for high efficiency without an external Schottky diode. It can be configured for either advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM) at light-load. AAM provides high efficiency by reducing switching losses, while FCCM has a controllable frequency and lower output ripple.

The MPQ2167B offers standard features including soft start, external sync clock, enable control, and a power good indicator. In addition, the device provides over-current protection with valley current detection to avoid current runaway. Additional safety features include short-circuit protection, reliable over-voltage protection, and auto-recovery thermal protection.

With internal compensation, the MPQ2167B requires a minimal number of readily available, standard external components, and is available in a QFN-11 (2mmx3mm) package.

EV2167B-D-00A 6V, 4A, Configurable-Frequency Buck Converter Evaluation Board

The EV2167B-D-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2167B, a configurable-frequency (300kHz to 2.2MHz), synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively). It provides up to 4A of continuous output current (I_OUT) with peak current control for excellent transient response.

The MPQ2167B 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 lower output ripple.

The EV2167B-D-00A is a fully assembled and tested evaluation board. It generates 1.8V of output voltage (V_OUT) at load currents up to 4A from a 2.7V to 6V input voltage (V_IN) range with a 1.9MHz switching frequency (f_SW).
