Description
LM3429 N-Channel Controller for Constant Current LED Drivers www.DataSheet4U.com PRELIMINARY LM3429 April 30, 2009 N-Channel Controller for Const.
Features
* include: precision reference, logic compatible DIM input suitable for fast PWM dimming, cycle-by-cycle current limit, and thermal shutdown. The LM3429 comes in a low profile, thermally efficient TSSOP EP 14-lead package. FeaturesApplications
* Adjustable high-side current sense with a typical sense voltage of 100 mV allows for tight regulation of the LED current with the highest efficiency possible. Output LED current regulation is based on peak current-mode control with predictive Off-Time Control. This method of control eases the desigLM3429 Distributors
