FAN2106 IC

Fairchild Semiconductor 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 ultracompact molded leadless package (MLP).

Measuring only 5-by-6mm, the FAN2106 is the industry's smallest 6A, 24V-input integrated synchronous buck regulator on the market today. This low-profile, small-footprint device consumes approximately 50 percent less board space than discrete solutions and facilitates greater design flexibility. FAN2106 also 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 suitable for use in different POL applications. These include STBs, 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."

FAN2106 features an integrated module that replaces one buck controller, two gate drivers and two MOSFETs. The device offers programmable switching-frequency feature that provides design flexibility. It also includes under-voltage, over-voltage, over-current and thermal protection circuitry which increases reliability. Moreover, its built-in selectable power-saving mode extends system battery life at light load.

The FAN2106 is available in an MLP Pb-free package that meets the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with EU regulations.

The device is available now and is priced at $3.78 each in 1000-unit quantities. Delivery is 10 weeks ARO. Samples, demo boards, application notes and field support are available for this product.
