General DescriptionThe FAN4855 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 converter 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. The
ON time changes with the input voltage to maintain the
ripple current constant and to provide the highest efficiency
over a wide load range—while maintaining low peak
currents in the boost inductor. The combination of built-in
power transistors, synchronous rectification and low supply
current, make the FAN4855 ideal for portable applications.
The FAN4855 is available in 8-lead MSOP and TSSOP
packages.
