■ GENERAL DESCRIPTION
The NJM2375/A are active power factor controllers, which limit the harmonic current resulting from the power supply block of electrical devices.
They include a startup timer, an one quadrant multiplier, a zero current detector to ensure critical condition operation, a transconductance error amplifier, high precision reference, a current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET. They also contain protection circuits for overvoltage, cycle-by-cycle overcurrent, and maximum peak current. The startup threshold of NJM2375A is lower than that of NJM2375.
