Buck/Boost Converter MP28167 by MPS

In a 3x3mm QFN Package

The MP28167 from MPS is a synchronous, 4-switch, integrated buck-boost converter, capable of regulating the output voltage across a 2.8V to 22V wideinput 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. It is available in a 16-pin QFN (3x3mm) package.

Flexible Design With Many Protective Functions

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.
