2.8V to 22V V_IN, 3A I_OUT, 4-Switch, Integrated Buck-Boost Converter with FB Pin

MPL

Description

MPL

Optimized Performance with MPS Inductor

The MP28167-A is a synchronous, four-switch, integrated buck-boost converter capable of regulating 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 automatic pulse-frequency modulation (PFM) mode, automatic pulse-width modulation (PWM) mode, and forced PWM switching mode. It also provides a configurable output constant current (CC) limit that supports flexible design for different applications.

Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), configurable soft start (SS), and thermal shutdown.

The MP28167-A is available in a QFN-16 (3mmx3mm) package.
