MP28168数据手册MPS中文资料规格书

描述 Description

The MP28168 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 efficiency. The integrated output voltage scaling and adjustable output current limit functions fit to different application requirement.
MP28168 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. MP28168 provides auto PFM/PWM or forced PWM switching modes, programmable output CC(Constant Current) current limit which supports flexible design for different applications.
The MP28168 also features with OCP/OVP/UVP, and thermal shutdown protection.
The MP28168 is available in a 16-pin QFN (3mmx3mm) package.
