EVL28167-A-Q-00A 22V, 3A, Synchronous Buck-Boost Converter with I2C Interface for Power Delivery Evaluation Board


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 (VOUT) across a wide 2.8V to 22V input voltage (VIN) range. Its integrated VOUT scaling and configurable output current (IOUT) 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.
