LM3492-Q1 Description
The LM3492/-Q1 integrates a boost converter and a two-channel current regulator to implement a high efficient and cost effective LED driver for driving two individually dimmable LED strings with a maximum power of 15 W and an output voltage of up to 65 V. The boost converter employs a proprietary ProjectedOn-Time control method to give a fast transient response with no pensation required, and a nearly constant...
