The EVL28167-N-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP28167-N, a high-efficiency, synchronous buck-boost converter with four integrated power switches and an I2C interface. The device can regulate the output voltage (VOUT) across a wide 2.8V to 22V input voltage (VIN) supply range.
The MP28167-N’s integrated VOUT scaling and configurable output current (IOUT) limiting functions are ideal for USB power delivery (PD) applications.
In buck mode, the MP28167-N 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-N 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-N requires a minimal number of readily available, standard external components, and it is available in a QFN-16 (3mmx3mm) package.
