2.8V-22V Vin, 3A Iout, 4-Switch Integrated
The Future of Analog IC Technology
PRELIMINARY SPECIFICATIONS SUBJECT TO CHANGE
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
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
