1 / 20 page  Isolated and Non-isolated Flyback LED Driver with Active PFC ZSLS7031 Datasheet © 2016 Integrated Device Technology, Inc. 1 January 26, 2016 Brief Description 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 con- stant 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 abnor- mally high operating temperatures. Benefits • High efficiency • Minimum bill of materials • Small form-factor package • No loop compensation required • Isolated and non-isolated applications Features • 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 Available Support • Evaluation Kit Physical Characteristics • Operating temperature:-45°C to 105°C • Maximum junction temperature: 150°C • Package: MSOP-8, RoHS-compliant ZSLS7031 Typical Isolated Application Q1 IC1 ZSLS7031 VSINE 1 FSET 3 GND 4 GATE 7 CS 6 FB 5 n.c. 2 VCC 8 D3 TR LED+ LED1 to LEDn LED- D4 C6 R8 C1 R1 R2 C2 Rset R3 C4 Rcs R9 C3 R5 C5 R6 R7 D2 D1 DB1 to DB4 L 85VAC to 265VAC N Fuse |
