MPQ4263-AEC1 3.6-36V, 280kHz Buck-Boost Converter QFN-20

MPQ4263-AEC1 3.6-36V, 280kHz Buck-Boost Converter QFN-20

Key Specifications

Features

• 140W Buck-Boost Converter with Integrated Low-Side MOSFETs (LS-FETs)
• Integrated Gate Driver for High-Side MOSFETs (HS-FETs)
• Configurable Input Under-Voltage Lockout (UVLO)
• 3.6V to 36V Start-Up Input Voltage (VIN) Range
• 1V to 36V Output Voltage (VOUT) Range
• Supports 2.8V Falling VIN When VOUT > 3.5V
• Up to 98% Peak Efficiency
• I2C-Configurable Reference Voltage (VREF) Range: 0.1V to 2.147V with 1mV Resolution
• Accurate Output CC Current Limit: ±5%, Supports High-Side Current Sense
• Accurate Output Current (IOUT) Monitor (IMON) Function

Applications

• USB PD Hubs
• USB PD Charging Ports
• Automotive DC Power 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.
• AEC-Q100 qualification suits this part to automotive rails.
• Package QFN-20 — check the land pattern in the datasheet before layout.
