MP28167GQ
DESCRIPTION
The 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 over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown.
The MP28167 is available in a 16-pin QFN (3mmx3mm) package.
