OFweek Semiconductor Lighting Network, Texas Instruments (TI) today announced a new single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimming solution not only regulates the LED current, but also achieves a power factor close to 1. The reference design achieves 85% efficiency and supports high-density small design solutions. The TPS92210 is suitable for general lighting applications such as commercial and residential recessed lights, ventilated lighting, bulb replacement products, architectural and display lighting.
Key features and benefits of the TPS92210:
1. The TPS92210 supports high-visibility working modes such as peak base current, constant on-time, and frequency modulation. Constant on-time mode uses single-stage power factor correction for improved efficiency;
2. Compared with competing devices, the TPS92210's cascading MOSFET configuration can reduce switching losses by 10% and enable easy startup;
3, continuous linear TRIAC dimming can achieve unified control without flicker;
4, no optoless over voltage protection (optoless over voltage protection), thermal shutdown and advanced overcurrent protection and other protection functions can safely shut down the system in the event of a failure;
5. Programmable fault response, complete shutdown, and shutdown restart provide greater flexibility for fault response.
