Here is the English information I found for the NCP51561DBDWR2G chip:

NCP51561DBDWR2G is a synchronous buck DC-DC converter from ON Semiconductor. Some key specs and features:

• Input voltage range: 4.5V to 18V
• Output voltage range: 0.6V to 5.5V
• Maximum output current: 6A
• Switching frequency: Up to 2MHz
• Integrated MOSFETs: High and low side
• Adjustable soft-start
• Synchronization capability
• Thermal shutdown
• Small 14-lead DFN and WSON packages

The NCP51561DBDWR2G is a synchronous step-down DC-DC converter suitable for powering microprocessors, FPGAs and other devices requiring up to 6A of output current. It uses an integrated high side and low side MOSFET pair to achieve high efficiency power conversion.

Key features include adjustable soft-start for reducing in-rush current, synchronization to an external clock for noise reduction, and thermal shutdown protection. The small package options make it well-suited for space-constrained applications.

In summary, the NCP51561DBDWR2G is a high efficiency synchronous buck regulator from ON Semiconductor capable of supplying up to 6A from a 4.5V to 18V input, in a small surface mount package. It offers integrated FETs, soft-start, synchronization and protection features.
