Linear constant current, high PF, high efficiency, low cost, and easy certification


The L1030 series is a linear constant current LED driver chip with power factor and efficiency, which outputs a critical energy storage mode linear constant current IC without flicker.

Adopting a patented critical energy storage linear constant motion circuit structure and control method, it has the advantages of high input power factor, no flicker output, and low EMI, meeting the mandatory provisions of relevant industry regulations. Built-in external programmable power limiting circuit, which limits the input power of the power grid when the mains voltage is high, reduces the power consumption of the driver, and reduces the cooling cost of the driver and lighting fixtures.

Adopting a 600V high-voltage semiconductor manufacturing process to ensure reliability during mains transients; An over temperature protection circuit is integrated internally to avoid thermal failure of the driver.
