General Description

The MPQ4214 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a wide input voltage range and high efficiency.

The MPQ4214 provides an I2C interface, which supports VOUT voltage programmability, VOUT slew-rate control, and constant output current limit programmability, making the MPQ4214 suitable for USB power delivery (PD) design in USB Type-C power supplies.

The MPQ4214 uses valley current control in buck mode and peak current control in boost mode, providing fast load transient response and smooth buck-boost mode transient.

Overview

MPQ4214 40V, Synchronous Buck-Boost Controller with I2C and Adjustable OCP via IPWM, AEC-Q100.

Key Features

  • hiccup over-current protection (OCP), auto-retry over-voltage protection (OVP), programmable soft start, and programmable under-voltage lockout (UVLO). The MPQ4214 is available in a QFN-27 (5mmx5mm) package, and it available in AECQ100 Grade 1.
