MP8860

2.8 - 22V V_IN, 1A I_OUT, 4-Switch,Integrated Buck-Boost Converter with I²C Interface

Active

Datasheet

Description

The MP8860 is a synchronous, 4-switch, integrated buck-boost converter capable of regulating the output voltage from a 2.8V to 22V wide input voltage range with high efficiency.

The MP8860 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 MP8860 provides auto PFM/PWM or forced PWM switching modes, and programmable output constant current (CC) 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), programmable soft start, and thermal shutdown.

The MP8860 is available in a 16-pin QFN (3mmx3mm) package.
