TPS92310 application circuit

description:

TI's TPS92310 is an off-line primary side detection PFC controller designed for high-power LED drivers for illumination, with constant on-time and quasi-resonant switching technology, high power factor, good EMI performance and high System efficiency. Mainly used in A19 (E26/27, E14), PAR30/38 and GU10 LED lights and solid state Lighting. This paper introduces the main features of the TPS92310, typical application circuit diagram

The TPS92310 is an off-line controller specifically designed to drive high power LEDs for lighting applications. With the primary side sensing, constant on-time and quasi-resonant switching techniques, the TPS92310 application circuit gives high Power Factor, good EMI performance and high System efficiency. Also, using this device, low external component count application solutions can be designed easily. Power Factor Correction is inherent if the TPS92310 is operated in the constant on-time mode with an adaptive algorithm. The control algorithm of TPS92310 adjusts the on -time with reference to the primary side inductor peak current and secondary side inductor discharge time dynamically, the response time of which is set by an external capacitor.
