ZSLS7031 Isolated and Non-isolated Flyback LED Driver with Active PFC Brief Description Features The ZSLS7031 is a primary-side controlled, peakcurrent-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 overvoltage protection, as well as a thermal shutdown to halt the switching action in the event of abnormally high operating temperatures. Available Support High efficiency Minimum bill of materials Small form-factor package No loop compensation required Isolated and non-isolated applications Evaluation Kit Physical Characteristics Benefits Power factor PF > 0.95 depending on application Wide application input voltage range: 85V to 265VAC Internal over-temperature protection Output over-voltage protection (OVP) Output over-current protection (OCP) on primary side Operating temperature:-45°C to 105°C Maximum junction temperature: 150°C Package: MSOP-8, RoHS-compliant ZSLS7031 Typical Isolated Application D4 LED+ + TR R5 C3 C6 85VAC to 265VAC R8 LED1 to LEDn Fuse LED- - L DB1 to DB4 R1 C1 R3 D1 D2 N D3 IC1 1 2 3 R2 4 C2 Rset ZSLS7031 VSINE n.c.
