The L6598D013TR is a power management specialised high voltage resonant controller manufactured by STMicroelectronics. It is designed to provide a highly efficient and highly integrated solution for switched mode AC/DC power supplies used in products such as TVs, monitors, printers, set top boxes, and other consumer electronics. The device includes digital and analog circuitry to provide a simplified two-loop control architecture for active PFC, traditional discontinuous-conduction-mode (DCM) PFC, and CCM buck forward implementations. It is designed to improve system efficiency and reduce overall component count, size, and cost. The device features integrated MOSFET drivers, optimized control loops, comprehensive protection, and comprehensive diagnostics.
