MP28167GQ-Z

MP28167 is a synchronous, 4-switch, integrated buck-boost converter, capable of regulating the output voltage across a 2.8V to 22V wide input voltage range with high efficiency. The MP28167 uses constant-on-time control in buck mode and constant-off-time control in boost mode, providing fast load transient response as well as smooth buck-boost mode transient. The MP28167 provides forced PWM switching mode and programmable output CC (constant current) limit, which supports flexible design for different applications. Full protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP) and thermal shutdown. The MP28167 is available in a 16-pin QFN (3mmx3mm) package.
