The ZSLS7031 is a primary-side controlled, peak-current-mode high-brightness LED flyback driver that supports both isolated and non-isolated designs with active power factor correction (PFC). The device works at a constant frequency in discontinuous conduction mode to provide constant power to the output. It eliminates the need for an opto-coupler, TL431 shunt regulator, or any other type of secondary-side feedback device. It operates from a wide input voltage range of 85VAC to 265VAC. The ZSLS7031 integrates over-current and over-voltage protection, as well as a thermal shutdown to halt the switching action in the event of abnormally high operating temperatures.
