Texas Instruments TPS92314 Off-Line Primary Side Sensing Controller with PFC in 8-SOIC TPS92314DR/NOPB

The TPS92314DR/NOPB is an off-line primary side sensing controller designed for driving high power LEDs in lighting applications. It features adaptive ON-time control with inherent power factor correction (PFC) and operates in critical conduction mode with zero current detection for valley switching, which enhances system efficiency and reduces electromagnetic interference (EMI). The device supports programmable switch turn-on delay and constant ON-time control, allowing for flexible design configurations. Protection features include over current limit options, with the TPS92314 offering a threshold of 1.15V and the TPS92314A a threshold of 2.0V, as well as internal over-temperature protection. The controller is packaged in an 8-pin SOIC format and is suitable for applications such as residential LED lamps and solid-state lighting. It operates over a supply voltage range of 13V to 35V and a temperature range of -40°C to +125°C, making it versatile for various environmental conditions.
