TPS92411PDBVR Datasheet PDF - TI

The TPS92411 is a 100-V floating MOSFET switch for use in offline LED lighting applications. The device is used in conjunction with a current regulator that can achieve a power factor greater than 0.9 to create a LED drive solution with low-ripple current. When properly designed, solution performance is comparable to traditional flyback, buck or boost-based AC/DC LED drivers. The approach requires no inductive components, thus saving size and cost. Slew-controlled low-frequency operation of the TPS92411 switches creates very little EMI. Detailed operation is described in the Application Information section.

●Package options include SOT23-5 and PSOP-8 allowing the user to optimize for small size or scale for high power. Using the PSOP-8 package, design of LED luminaires up to 70 W or more is possible. Other features include a UVLO circuit to monitor when the device has sufficient voltage to operate properly and over-voltage protection (TPS92411P).
