Key Features
- 6 A output current with 2.4 V to 5.5 V input range and I2C-programmable output voltage from 0.4 V to 1.675 V
- Current-mode PWM control in a 1.05 mm × 1.78 mm WCSP footprint — among the smallest 6 A converters available
- I2C interface enables real-time dynamic voltage scaling for processor and FPGA core rail optimization
Applications
The XPS628660AYCGR is optimized for powering processor cores, FPGAs, and memory rails in ultra-compact wearables, IoT modules, and miniaturized computing platforms where board space is extremely limited. Its I2C interface supports dynamic voltage scaling, allowing host processors to adjust the core rail voltage in real time to minimize power consumption during idle states. The 6 A current capability also supports high-performance SoCs that draw brief bursts of current during intensive workloads.

Frequently Asked Questions
What input voltage range does the XPS628660AYCGR support, and what output voltage can it regulate to?
The XPS628660AYCGR accepts inputs from 2.4 V to 5.5 V and produces an adjustable output from 0.4 V to 1.675 V, making it suitable for powering 0.9 V FPGA cores and 1.5 V DDR memory from a 3.3 V or 5 V system rail.
How does the I2C interface on the XPS628660AYCGR enable dynamic voltage scaling?
The I2C interface allows a host MCU or processor to change the output voltage set-point in real time across the 0.4 V to 1.675 V range, enabling dynamic voltage and frequency scaling techniques that reduce SoC power consumption by up to 30% during low-activity periods.
What makes the XPS628660AYCGR WCSP package unusually compact for a 6 A converter?
The wafer-chip-scale package measures only 1.05 mm × 1.78 mm — smaller than a grain of rice — yet supports 6 A continuous output current, making it the right choice when every square millimeter of board space is critical in wearable or hearing-aid PCB designs.
Which control topology does the XPS628660AYCGR use, and how does that affect transient response?
It uses current-mode pulse-width modulation, which provides inherent cycle-by-cycle current limiting and faster load transient response compared to voltage-mode control, important for processor rails experiencing rapid current steps of 3 A or more in microseconds.
