MP28167-N 2.8-22V, 3A, 500kHz Buck-Boost Converter QFN-16

MP28167-N 2.8-22V, 3A, 500kHz Buck-Boost Converter QFN-16

Key Specifications

Features

• Configurable Output Voltage (VOUT) via the Feedback (FB) Pin
• Wide 2.8V to 22V Operating Input Voltage (VIN) Range
• 0.08V to 1.637V Reference Voltage (VREF) Range with 0.8mV Resolution via the Digital Interface (1) (Default 1V VREF)
• Up to 3A Output Current (IOUT) or 4A Input Current (IIN)
• Four Low On Resistance (RDS(ON)), Internal Buck Power MOSFETs
• Adjustable Accurate Output Constant Current (CC) Limit with Internal Sensing MOSFET via the Digital Interface
• 500kHz, 750kHz, 1MHz, or 1.25MHz Selectable Switching Frequency (fSW)
• Output Over-Voltage Protection (OVP) with Hiccup Mode
• Output Short-Circuit Protection (SCP) with Hiccup Mode
• Over-Temperature Warning and Shutdown

Applications

• Solid-State Drives (SSDs)
• USB Power Delivery (PD) Sourcing Ports
• Buck-Boost Bus Supplies

Design Notes

• Buck-boost operation keeps the output regulated either side of the input, which costs efficiency compared with a pure buck at the same rating.
• Power switches are integrated, so the thermal path is the PCB copper under the pad.
• Package QFN-16 — check the land pattern in the datasheet before layout.
