2.8V-22V Vin, 3A Iout, 4-Switch Integrated Buck-Boost Converter
The MP28167 is a synchronous 4-switch integrated buck-boost converter, which is capable of regulating the output voltage from 2.8V to 22V wide input voltage range with high efficiency.
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. MP28167 provides forced PWM switching mode, programmable output CC(Constant Current) current limit which supports flexible design for different applications.
The MP28167 also features with OCP/OVP/UVP, and thermal shutdown protection.
The MP28167 is available in a 16-pin QFN(3mmx3mm) package.
