10-A buck regulator delivers efficiency and power density benefits

November 21, 2011 // By Paul Buckley
Intersil Corporation has introduced a new 10 A integrated FET synchronous buck regulator featuring excellent efficiency and power density.

The ISL95210 provides a very dense DC/DC converter solution with up to 45% total area reduction over alternative solutions. The device is a highly efficient, single-output buck regulator that requires only four external components. Intersil’s patented R4 control architecture claims to provide exceptional transient response with no external compensation components. The regulator is ideal for wide range of applications including point of load (POL) power supplies for computing and networking infrastructure equipment.
An internal DAC is programmed by two external pins, and allows designers to select from nine different regulator output voltages.  Several digital control signals provide flexibility to program switching frequency, switching mode, output voltage margining and a daisy-chained power-good output. The ISL95210 also includes comprehensive internal protection for overvoltage, undervoltage, overcurrent and overtemperature conditions.

Availability and Pricing

The ISL95210 is available in a compact, 4 mm x 6 mm, 32-pin QFN package. Pricing starts at $3.25 each in 1,000-piece quantities.
