MPQ4214 Datasheet | Monolithic Power Systems

40V, Synchronous Buck-Boost Controller with I2C and Adjustable OCP via IPWM, AEC-Q100 Qualified 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. The MPQ4214 offers forced continuous conduction mode (FCCM) and a programmable average current limit, which supports flexible designs for different applications. The MPQ4214 also 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.
