L6561,Transition Mode Power Factor Correction Controller,DIP-8

The L6561 is a high-performance transition mode power factor correction (PFC) controller from STMicroelectronics, engineered for energy-efficient power conversion systems. Its precise internal reference voltage, low startup current of 50uA, and operating current of 4mA make it an ideal choice for low-power applications like AC-DC adapters, electronic ballasts, and small SMPS systems.

Built-in protection features such as overvoltage protection, undervoltage lockout, and a disable function ensure safe operation and enhanced reliability. The L6561 offers a robust +/-400mA gate drive capability, supporting high-speed switching for MOSFETs and IGBTs. Designed for ease of use, the device minimizes the need for external components, simplifying circuit design while achieving excellent power factor correction and low harmonic distortion.

The L6561 is housed in a compact DIP-8 package, making it easy to integrate into space-constrained designs. Its exceptional performance and efficiency make it a trusted solution for modern power electronics.
