Tiny regulator steps down in size

DC/DC buck regulator combines an advanced analogue IC, MOSFETs and a boot diode into an ultracompact moulded leadless package.

New from Fairchild Semiconductor, the FAN2106 is the first product in a new family of TinyBuck DC/DC buck regulators that integrate an advanced analogue IC, MOSFETs and a boot diode into an ultracompact moulded leadless package (MLP).

Measuring only 5 x 6mm, the FAN2106 is claimed to be the industry's smallest 6A, 24V-input integrated synchronous buck regulator on the market today.

This highly integrated low-profile, small-footprint device consumes approximately 50% less board space than discrete solutions and facilitates greater design flexibility.

Furthermore, the FAN2106 achieves up to 95% power efficiency by converting inputs from 3 to 24V to output voltages as low as 0.8V while delivering up to 6A output current.

This compact easy-to-use high-efficiency regulator is ideal in a broad range of point-of-load (POL) applications.

These include set-top boxes, cable modems, in-cabin GPSs, portable medical equipment, LED lighting, industrial instrumentation as well as ultramobile PCs, notebooks and blade servers.

"Fairchild's TinyBuck all-in-one module offers superior features that enable engineers to meet their primary design challenges: saving board space, simplifying designs and increasing power efficiency", says Justin Chiang, Vice President of Fairchild's System Power Group.

"As the first product in this new family, the FAN2106 integrates our latest DC/DC PWM controller with gate drivers, advanced MOSFETs and a boot diode into a tiny MLP package".

"Combining Fairchild's power supply engineering expertise in silicon design and state-of-the-art device packaging technology, this product provides a complete silicon power solution".
