Product Summary
The FAN4855MTCX is a low power boost regulator designed for low voltage DC to DC conversion in 2-cell battery powered systems such as digital cameras, cell phones and PDAs. The FAN4855MTCX starts-up at 1.3V and operates after the start at an input voltage as low as 1V. Output voltage can be adjusted by external resistors from 3.3V to 5V with a maximum load current of 0.5A. Quiescent current in shut-down mode is less than 10μA, which maximizes the battery live time. Applications of the FAN4855MTCX are (1)DSCs; (2)PDAs; (3)Cell phones, smart phones; (4)Portable instrumentations; (5)2-3 AA / AAA cells operated devices; (6)Single cell Li-Ion operated devices.
