Intersil has a 10A integrated FET synchronous buck regulator. The single-output buck regulator is designed to require only four external components.

The company uses a novel control architecture which it claims will provide good transient response with no external compensation components.

An internal DAC is programmed by two external pins, and allows designers to select from nine different regulator output voltages. 

The ISL95210 also includes internal protection for overvoltage, undervoltage, overcurrent and overtemperature conditions.

It is available in a 4mm x 6mm, 32-pin QFN package.
