L6565 Quasi-Resonant SMPS Controller SMD IC

L6565 Quasi-Resonant SMPS Controller SMD IC

The L6565 is a Quasi-Resonant SMPS (Switched-Mode Power Supply) Controller SMD IC designed to optimize power conversion efficiency in high-performance, low-power applications. This IC is particularly suited for use in fly back converters, which are common in power supplies for various consumer electronics, lighting, and industrial equipment. The quasi-resonant operation enables the L6565 to minimize switching losses by operating at the most efficient points of the power cycle. Key features of the L6565 include primary side control and quasi-resonant operation, which help achieve higher efficiency and lower electromagnetic interference (EMI) compared to conventional fixed-frequency controllers. The IC integrates various protective functions such as over-voltage protection (OVP), over-current protection (OCP), and under-voltage lockout (UVLO) to enhance system reliability and protect against fault conditions. The L6565's design promotes lower heat dissipation and a reduced component count in the power supply circuit, making it a cost-effective solution. With a wide supply voltage range and low startup current, this controller is well-suited for energy-efficient power supply designs that comply with modern energy standards.
