EVL28167-A-Q-00A

EVL28167-A-Q-00A is an evaluation board for the MP28167-A, a high-efficiency, synchronous buck-boost converter with four integrated power switches and an I2C interface. Device can regulate output voltages across a wide input voltage supply range (2.8V to 22V). The MP28167-A’s integrated output voltage scaling and configurable output current limit functions 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 buckboost mode transient. It 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. MP28167-A is available in a QFN-16 package. Used in USB power delivery for sourcing ports and buck-boost bus voltage supplies.
