DESCRIPTION
The MP28167-A is a synchronous, four-switch, integrated buck-boost converter capable of regulating the output voltage across a wide 2.8V to 22V input voltage range with high efficiency. The integrated output voltage scaling and adjustable output current limit functions meet USB power delivery (PD) requirements.
The MP28167-A uses constant-on-time (COT) control in buck mode and constant-off-time control in boost mode, providing fast load transient response and smooth buck-boost mode transient. The MP28167-A provides autoPFM/PWM or forced PWM switching modes. It also provides configurable output constant current (CC) current limit, which supports flexible design for different applications.
