• Supports USB PD 3.1, EPR AVS, and PPS specifications via configurable I2C interface
• Provides accurate output current monitoring and high-side current sense support
• Features special buck-boost control strategy for smooth transient response across modes

Applications

• USB PD Hubs
• Automotive DC power supplies
• Wireless charging applications

Procurement Notes

Verify the specific suffix '0001' against official MPS documentation to confirm exact configuration details, as ordering suffixes may denote specific package or testing variations. Ensure compatibility with AEC-Q100 requirements for your target automotive application. Cross-reference the wettable flank package type if lead inspection is required by your manufacturing standards.

Selection Notes

Select this component when designing systems requiring high power density up to 140W in an automotive environment. The integrated low-side MOSFETs reduce external component count compared to discrete solutions. Consider the selectable switching frequencies to optimize for either size or efficiency needs. The I2C interface allows for dynamic adjustment of reference voltages and operational modes.
