MPQ4210集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

DESCRIPTION

The MPQ4210 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a wide input voltage range and high efficiency. It provides an I2C interface, which supports VOUT voltage programmability, VOUT slew-rate control, and output constant 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 forced continuous conduction mode (FCCM) and a programmable average current limit, which supports flexible designs for different applications.

It also features programmable over-current protection (OCP) mode, programmable overvoltage protection (OVP) mode, and programmable VIN UVLO hysteresis.

The MPQ4210 is available in a QFN-27 (5mmx5mm) package.
