Overview

IS31LT3929 General Description Preliminary Features • • • • • Power factor correction to > 0.
9 3% typical current accuracy No loop compensation required Wide input voltage range: 85V to 265VAC Internal over-temperature protection Flyback configuration LED driver with integrated PFC and no feedback The IS31LT3929 is a primary side, peak current mode, isolated type HBLED driver.
The device works at a constant frequency in discontinuous conduction mode to provide a constant power to the input.
It eliminates the need for an opto-coupler, TL431, or any other type of secondary side feedback.
It operates from an input voltage range of 85VAC to 265VAC.
The IS31LT3929 integrates over current/volta...
