FAN5602 Description

    The FAN5602 is a universal switched capacitor DC/DC converter 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 efficiency 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 current drawn from the supply. The device is protected against short circuit and over temperature conditions.
