MP8859 Description
The MP8859 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 integrated output voltage scaling and adjustable output current limit functions meet the USB power delivery (PD) requirement. The MP8859 uses constant-on-time (COT) control in buck mode and constant-off-time control in boost mode,...
