EV8859-Q-00B

2.8V-22V Vin, 3A Iout, 4-Switch Integrated Buck-Boost Converter with I2C Interface

Datasheet

Description

The EV8859-Q-00B is an evaluation board for MP8859, which is a synchronous 4-switch integrated buck-boost converter. It can regulate 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 the USB Power Delivery (PD) requirement.

MP8859 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. MP8859 provides auto PFM/PWM or forced PWM switching modes, programmable output CC(Constant Current) current limit which supports flexible design for different applications.

The MP8859 also features with OCP/OVP/UVP, programmable soft-start and thermal shutdown protection.

The MP8859 is available in a 16-pin QFN(3mmx3mm) package.
