Overview
IS31LT3916 Offline LED driver with active PFC and primary side sensing General Description Features February 2013 The IS31LT3916 is a primary side, peak current mode, isolated or non-isolated type HBLED driver.
The device works at a constant frequency in discontinuous conduction mode to provide a constant power to the output.
It eliminates the need for an opto-coupler, TL431, or any other type of secondary side feedback.
It operates from a wide input voltage range of 85VAC to 265VAC.
The IS31LT3916 integrates over current protection, over voltage protection, as well as includes a thermal shutdown to halt the switching action in the case of abnormally high operating temperatures.
 Power factor correction to > 0.
95  5% typical current accuracy  High efficiency  No loop compensation required  Wide input voltage range: 85V to 265VAC  Isolation and Non-isolation application  Internal over-temperature protection  Over voltage protection  Primary side over current protection Applications  LED bulb lamp  LED tube lamp  General LED Lighting Typical Operating Circuit Figure 1 Typical Operating Isolated Circuit Integrated Silicon Solution, Inc.
