Frequently Asked Questions
How does the TPS92310 regulate LED current without secondary-side feedback?
The TPS92310 uses primary-side regulation to control a single LED channel output current with an accuracy of typically ±5%. It monitors the demagnetization waveform on the primary side to estimate secondary current, eliminating the opto-coupler and secondary-side sense resistor typically required in flyback designs. This reduces BOM cost while maintaining tight regulation across load and line variations.
What input voltage range does the TPS92310 support for offline LED lighting?
The TPS92310 supports a universal AC input voltage range, typically 85 VAC to 265 VAC, making it compatible with worldwide mains voltages including 100 V, 110 V, 120 V, 220 V, and 240 V systems. Its internal high-voltage startup circuit allows direct connection to rectified AC rails without an external startup resistor, simplifying the power stage design.
Which LED lighting form factors are best matched with the TPS92310 flyback controller?
The TPS92310 is ideal for LED bulbs, LED tube replacements, and LED retrofit lamps that must fit within tight enclosures. Its single-channel output and 10-pin MSOP package allow designs with a small PCB footprint under 1 cm², supporting lamp wattages typically from 3 W to 25 W. Industrial downlights and commercial panel lights also benefit from its simplified driver topology.
How does the TPS92310 compare to designs using an opto-coupler for LED driver feedback?
By eliminating the opto-coupler, the TPS92310 reduces component count by at least 4-6 parts and lowers overall system cost. Traditional opto-coupler designs require a secondary-side error amplifier, precision reference, and the opto-coupler itself, while TPS92310 integrates equivalent regulation using only primary-side winding sensing. This also improves reliability since opto-couplers degrade over time at elevated temperatures above 85°C.
