Introducing Fairchild Semiconductor's TinyBuck™”

First in a new family of all-in-one regulators, the MLP-packaged FAN2106 offers up to 95 percent efficiency to improve system thermal performance while simplifying designs.

Fairchild Semiconductor (NYSE: FCS) introduces the FAN2106, the first product in a new family of TinyBuck™ DC-DC buck regulators that integrate an advanced analog IC, MOSFETs and a boot diode into an ultra-compact molded leadless package (MLP). Measuring only 5mm x 6mm, the FAN2106 is 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 percent less board space than discrete solutions and facilitates greater design flexibility. Furthermore, the FAN2106 achieves up to 95 percent power efficiency by converting input of 3V through 24V input voltages 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 ultra-mobile 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,” said 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 that further strengthens the company’s leadership position as The Power Franchise®.”

Key features of the FAN2106 include:
Wide input range: 3V to 24V.
Integrated module replaces one buck controller, two gate drivers and two MOSFETs.
Saves 50 percent voltage-regulator real estate since TinyBuck’s MLP is smaller than two SOIC packages.
Integrated boot diode minimizes board space.
Programmable switching-frequency feature provides design flexibility.
Under-voltage, over-voltage, over-current and thermal protection circuitry increases reliability.
Built-in selectable power-saving mode extends system battery life at light load.
The FAN2106 is available in an MLP lead (Pb)-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with European Union regulations now in effect.
