The NJM2375/A is an active power‑factor controller that limits harmonic current in power‑supply blocks. It integrates a startup timer, one‑quadrant multiplier, zero‑current detector, error amplifier, high‑precision reference, current‑sensing comparator and a totem‑pole output for driving power MOSFETs, plus protection for over‑voltage, over‑current and peak‑current conditions.
The document provides detailed electrical characteristics, absolute maximum ratings, pin configuration, typical application circuits and performance graphs, enabling designers to select and implement the device in power‑conversion solutions.
