Product Description

The MPQ4210 is a full-feature, buck-boost controller to support USB PD3.0 power solutions for automotive USB power designs. The MPQ4210 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a 4V to 40V wide input voltage range and high efficiency. The MPQ4210 provides an I2C interface, which supports VOUT voltage programmability, VOUT slew-rate control and constant output current limit programmability, making the MPQ4210 suitable for USB power delivery (PD) design in USB Type-C power supplies. The MPQ4210 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 MPQ4210 provides power-save mode (PSM), forced continuous conduction mode (FCCM) switching mode and programmable average current limit, which supports flexible designs for different applications. The MPQ4210 also features hiccup over-current protection (OCP), hiccup over-voltage protection (OVP), programmable soft start, and programmable under-voltage lockout (UVLO). The MPQ4210 is available in a QFN-27 (5mmx5mm) QFN package.
