Texas Instruments added a new off-line primary side sensing controller to its portfolio of non-dimming LED drivers. The TPS92310 AC/DC constant current driver with power factor correction (PFC) is suitable for high-power LED retrofit bulbs, including A19, PAR30/38 and GU10.
The device’s AC input voltage supports common line voltages of 100 V, 120 V, 230 V, 240 V and 277 V. True primary side sensing and regulation provides accurate LED current regulation, eliminating optocoupler, secondary error amplifier and associated passive components.
Two operating modes are available: adaptive constant on-time (COT) mode provides inherent power factor correction with no external components, while peak current control provides low LED current ripple to minimise stroboscopic effects.
Critical conduction mode (CCM) with zero current detection (ZCD) provides valley switching for improved power conversion efficiency and low EMI. Cycle-by-cycle current limit, over/under-voltage protection and thermal shutdown protect the LED driver and user against faults and abnormal operating conditions.
