MPL

The EVL28167-B-Q-00A is an evaluation board for the MP28167-B, a high-efficiency, synchronous buck-boost converter with four integrated power switches and an I²C interface. The device can regulate the output voltage (V_OUT) across a wide 2.8V to 22V input voltage (V_IN) range.

In buck mode, the MP28167-B uses constant-on-time (COT) control. In boost mode, it uses constant-off-time control. This provides fast load transient response and smooth buck-boost mode transient. The MP28167-B features automatic pulse-frequency modulation (PFM) and pulse-width modulation (PWM) modes, forced PWM mode, as well as configurable constant current (CC) limiting and soft start (SS). These features provide flexible design options for different applications.

The MP28167-B’s fault protections include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), short-circuit protection (SCP), and thermal shutdown (TSD).

The MP28167-B requires a minimal number of readily available, standard external components, and is available in a QFN-16 (3mmx3mm) package.

It is recommended to read the datasheet for the MP28167-B prior to making any changes to the EVL28167-B-Q-00A.
