MPL

The EVL28167-A-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP28167-A, a high-efficiency, synchronous buck-boost converter with four integrated power MOSFETs and an I²C interface. It can regulate output voltages (V_OUT) across a wide 2.8V to 22V input voltage (V_IN) range. Its integrated V_OUT scaling and configurable output current (I_OUT) limit are ideal for USB power delivery (PD) applications.

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

The MP28167-A’s fault protections include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), short-circuit protection (SCP), and thermal shutdown. The MP28167-A requires a minimal number of readily available, standard external components, and is available in a QFN-16 (3mmx3mm) package.
