EV8862-Q-00A

The EV8862-Q-00A is an evaluation board for MP8862, which 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 MP8862 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 MP8862 provides auto PFM/PWM or forced PWM switching modes, programmable output constant current (CC) current limit, which supports flexible design for different applications. Full protection features include OCP, OVP, UP, programmable soft start and thermal shutdown. The MP8862 is available in a 16-pin QFN (3mmx3mm) package.
