FA5500AP/AN and FA5501AP/AN are power supply control ICs for power factor correction provided by Fuji Electric. They are mainly used in AC-DC power converters.
The FA5500AP/AN and FA5501AP/AN are CMOS power‑factor‑correction control ICs that operate in critical conduction mode. They feature low current consumption, a compensated current‑sense comparator for light‑load regulation, open/short protection on the feedback pin, undervoltage lockout, over‑voltage protection, and a restart timer. The devices are offered in DIP‑8 and SOP‑8 packages.
The datasheet includes a block diagram, detailed pin‑assignment table, absolute‑maximum and recommended operating ratings, characteristic curves, and example application circuits. It also gives design advice for implementing the ICs in power‑supply designs and outlines ON/OFF control methods.
