$5000L4981BD
L4981BD is a Power Factor Correction PWM Controller with a low current consumption of 0.3mA and a frequency of 115KHz, packaged in a 20-pin SO tube
L4981BD 概要
The L4981BD is a cutting-edge power factor corrector that enables the development of high-efficiency power supplies with a remarkable power factor of up to 0.99. Designed using advanced BCD 60II technology, this IC offers a comprehensive set of control functions for achieving sinusoidal line current consumption. Operating seamlessly within mains voltages ranging from 85V to 265V, the L4981BD eliminates the need for a line switch, simplifying system design and enhancing reliability. Whether operating in fixed frequency mode (L4981A) or modulated frequency mode (L4981B), this PFC regulator ensures optimal performance and control, maintaining sinusoidal line current without slope compensation. Equipped with essential features such as a power MOSFET gate driver, voltage reference, error amplifier, and integrated protections such as overvoltage and overcurrent protection, the L4981BD offers a streamlined solution for efficient power supply design
