Texas Instruments TPS92411 100V Floating MOSFET Switch

Texas Instruments TPS92411 100V Floating MOSFET Switch

TPS92411 MOSFET Switch

Texas Instruments TPS92411 100V floating MOSFET switch is used in conjunction with a current regulator that can achieve greater than 0.9 power factor to create an offline 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 saving size and cost. Slew controlled low frequency operation of the TPS92411 switches creates very little EMI. 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 the LED luminaires up to 70W is possible. Other features include a UVLO circuit to monitor when the device has sufficient voltage to operate properly and over voltage protection (TPS92411P).

TPS92411EVM-001 / TPS92411EVM-002 EVMs

Texas Instruments TPS92411EVM-001 and TPS92411EVM-002 evaluation modules help designers evaluate the operation and performance of the TPS92411P direct drive switch. TPS92411EVM-001 implements a 120VAC, 12W, phase dimmable light engine with high power factor and low LED current ripple on a single-sided metal core printed circuit board. The included LED drive circuit is comprised of a high voltage linear regulator and TPS92411 floating switches arranged to toggle three segments of a high-voltage LED string at eight discrete points during an AC half-cycle. Unlike traditional switched mode power supply converters, TPS92411EVM-001 uses no magnetic components or high speed switching for power processing. TPS92410VEVM-002 implements a 230V linear regulator dimming solution using the TPS92410 Switch Controlled Direct Drive Linear Controller and TPS92411 100V Floating MOSFET Switch.
