FAN5602 is a universal switched capacitor DC/DC converter capable of step-up or step-down operation from 2.7V to 5.5V input voltage. It features adaptive fractional switching topology, resistance-modulated loop control, and automatic constant-frequency/pulse-skipping mode selection to achieve high efficiency over a wider input/output voltage range and minimize switching noise.
The FAN5602 is a universal switched capacitor DC/DC converter capable of both step-up and step-down operation. It utilizes an adaptive fractional switching topology to achieve high efficiency across a wide input/output voltage range, automatically reconfiguring the system based on load conditions.
The device operates with a minimum external component count, requiring only two 1µF bucket capacitors and one output capacitor. It features low-noise constant-frequency operation at heavy loads and pulse-skip (PFM) mode at light loads to extend battery life. The FAN5602 is available in 4.5V and 5.0V output versions within a 3x3mm 8-lead MLP package.
