LM3414HV 1A 65V LED Driver Evaluation Board LM3414HV 1A 65V LED Driver Evaluation Board National Semiconductor Application Note 2076 SH Wong August 10, 2010 Introduction The LM3414HV is a 65V floating buck LED driver that designed to drive up to 18 pieces of serial High Brightness LEDs (HBLEDs) with up to 1000mA LED forward current.

With the incorporation of the proprietary Pulse-Level-Modulation (PLM) technology, the LM3414HV requires no external current sensing resistor to facilitate LED cu

LM3414HV Features

* a dimming control input (DIM pin) that allows PWM dimming control. The LM3414HV is available in LLP-8 (3mm x 3mm outline) and ePSOP8 to fulfil the requirements of small solution size and high thermal performance respectively. In order to demonstrate the performance of the LM3414 family, the LM3414HV
