DC-DC Switching Buck-Boost Regulator, 2.8-28 V in, 3 A out, 750 KHz, QFN-16 Product Overview MP28167-A is a synchronous, 3A IOUT, four-switch, integrated buck-boost converter capable of regulating the output voltage across a wide 2.8V to 22V input voltage range with high efficiency. The integrated output voltage scaling and adjustable output current limit functions meet USB power delivery (PD) requirements. The MP28167-A uses constant-on-time (COT) control in buck mode and constant-off-time control in boost mode, providing fast load transient response and smooth buck-boost mode transient. The MP28167-A provides autoPFM/PWM or forced PWM switching modes. It also provides configurable output constant current (CC) current limit, which supports flexible design for different applications. Full protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), configurable soft start and thermal shutdown. It is available in a QFN-16 (3mmx3mm) package. Applications include USB PD sourcing ports and buck-boost bus supplies. Configurable output voltage via the FB pin 0.08V to 1.637V reference voltage (VREF) range with 0.8mV resolution via I2C (default VREF is 1V ) 3A output current or 4A input current, four internal and low RDS(ON) power MOSFETs Adjustable accurate CC output current limit with internal sensing MOSFET via I2C 500KHz/750KHz configurable switching frequency Overvoltage protection (OVP) with hicc-up mode, short circuit protection (SCP) with hicc-up mode Overtemperature warning and shutdown I2C interface with ALT pin, one-time programmable (OTP) non-volatile memory I2C-configurable line drop compensation, PFM/PWM mode, soft start, OCP and OVP Configurable EN shutdown discharge, MPL-AL inductor series matches the best performance Product Information Topology: Synchronous Buck-Boost Input Voltage Min: 2.8V Input Voltage Max: 22V DC / DC Converter IC Case: QFN No. of Pins: 16Pins Output Current: 3A Switching Frequency: 750kHz Operating Temperature Max: 125°C MSL: MSL 1 - Unlimited
