IS31LT3916
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
