Description : 1A 60W* COMMON ANODE CAPABLE CONSTANT CURRENT BUCK LED DRIVER REQUIRES No External CURRENT Sensing Resistor View

General Description
The LM3414 and LM3414HV are 1A 60W* COMMON ANODE CAPABLE CONSTANT CURRENT BUCK LED DRIVERs. They are exceptionally suitable to drive single string of 3W HBLED with up to 96% efficiency. They accept input voltages from 4.5VDC to 65VDC and deliver up to 1A average LED CURRENT with ±3% accuracy. The integrated low-side N-channel power MOSFET and CURRENT sensing element realize simple and low component count circuitry as no bootstrapping capacitor and external CURRENT sensing resistor are required. An external small signal resistor to ground provides very fine LED CURRENT adjustment, analog dimming as well as thermal fold-back functions.
