OB3340 Overview
The OB3340 is a high power factor and high constant current precision LED driver for LED lighting applications. An analog multiplier for power factor correction (PFC), zero current detector (ZCD) to ensure TM operation and a feedback circuit to achieve constant LED current, a current sensing parator with built-in leadingedge blanking ensures safe operation during short-circuit at the output, and a totem pole output...
