Description
The FAN5602 is a universal switched capacitor DC/DC con-
verter capable of step-up or step-down operation. Due to its
unique adaptive fractional switching topology, the device
achieves high efficiency over a wider input/output voltage
range than any of its predecessors. The FAN5602 utilizes
resistance modulated loop control, which produces lower
switching noise than other topologies. Depending upon
actual load conditions, the device automatically switches
between constant frequency and pulse skipping (PFM)
modes of operation in order to extend battery life. The
FAN5602 produces a fixed regulated output within the range
of 2.7V to 5.5V from any type of voltage source. High effi-
ciency is achieved under any input/output voltage conditions
because an internal logic circuitry automatically reconfigures
the system to the best possible topology. Only two 1μF
bucket capacitors and one 10μF output capacitor are needed.
During power on soft start circuitry prevents excessive cur-
rent drawn from the supply. The device is protected against
short circuit and over temperature conditions.
The FAN5602 is available with 3.3V, 4.5V, and 5.0V output
voltage. Any other output voltage option within the 1.5V to
5V range is available upon request. The FAN5602 is avail-
able in 8-lead MSOP and 3x3mm 8-lead MLP packages
