5V 300mA TinyBoost Regulator from Fairchild

Fairchild Semiconductor has introduced the FAN4860, a 5V 300mA TinyBoost regulator, that offers power for USB On-the-Go (OTG) and HDMI communication circuits and is said to provide a high level of efficiency as well as a small form factor. It is targeted to enable communication between portable devices such as cell phones, smartphones, digital cameras and other devices.

The device has a switching frequency of 3MHz frequency thus allowing the use of small capacitors and inductors. This regulator has a low quiescent current, a VIN of 3.6V at light load (1mA). It is said to offer efficiency of 84 percent and at 200mA load. In addition, the true load-disconnect between the battery and the load eliminates the leakage from the battery during the OFF state, extending the phone's shutdown life. It is also said to offer excellent transient response even with a small output capacitor. This solution supports the quick design cycles found in the mobile device market and is suggested for cell phones, smartphones, PMPs and lithium-ion portables.

The FAN4860 complements Fairchild's core power and battery management solutions, including the FAN5361, a 6MHz 600mA Buck regulator that allows the use of tiny 470nH chip inductors and 0402 case size input and output capacitors, as well as the FAN5355, an 800mA/1000mA 3MHz Buck converter equipped with an I2C interface for dynamic voltage scaling.
