TI Introduces New LED Lighting Controller with Power Factor Correction
Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a new single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC-dimmable solution regulates LED current and also achieves near unity power factor. The reference design can achieve 85 percent efficiency, which…
Key features and benefits of the TPS92210:
• TPS92210 features flexible operation modes such as peak primary current, constant on-time and frequency modulation. The constant on-time mode provides single-stage power factor correction for improved efficiency.
• TPS92210's cascoded MOSFET configuration results in 10 percent lower switching losses with fast and easy high-voltage start-up compared to competitive devices.
• Continuous linear TRIAC dimming provides flicker-free, uniform control.
• Multiple protection features, such as over voltage protection without optocouplers, thermal shutdown and advanced over current, safely shut down the system if fault conditions exist.
• Programmable fault response, full shutdown and shutdown restart provide added flexibility for fault response.
