The TPS92314DR from Texas Instruments is an off-line primary side sensing controller with Power Factor Correction (PFC), specifically engineered for driving high-power LEDs in various lighting applications. This controller utilizes adaptive constant on-time control and quasi-resonant switching, enabling efficient operation.
Key electrical specifications include an input voltage range of 13V to 35V AC/DC, with a maximum output voltage of 60V and a maximum output current of 2A. It operates with a typical quiescent current of 1.2mA and features adjustable switch frequency, soft switching, and thermal shutdown for robust performance. The operating temperature range is from -40°C to 125°C.
The device supports analog dimming and offers programmable switch turn-on delay and programmable constant on-time (COT). It incorporates advanced over-current and over-voltage protection, along with internal over-temperature protection. The TPS92314DR is housed in an 8-SOIC package, suitable for surface mount applications.
This controller regulates LED current without requiring secondary-side sensing, simplifying system design. Its critical-conduction-mode (CRM) operation with zero-current detection (ZCD) facilitates valley switching for improved efficiency.
