This is a high efficiency offline LED lighting controller, which adopts frequency fold back and low power mode operation to reduce the operation frequency at light load and no load. The controller integrates advanced energy saving features to provide high efficiency driving for LED lighting applications.
The TPS92010 is an 8‑pin PWM controller designed for LED lighting applications. It offers quasi‑resonant operation, low standby current, and programmable over‑voltage and over‑temperature protection. The device is supplied in a SOIC‑8 package and operates from –40 °C to 105 °C.
Key features include a 1.2 A peak sink current, 0.8 A source capability, UV‑LDO protection, and a soft‑start pin for controlled power‑up. The datasheet provides absolute maximum ratings, recommended operating conditions, pin functions, and mechanical dimensions.
