The Texas Instruments LM3414HV is a 1-A, 60-W common anode-capable constant current buck LED driver designed for high-power LED applications. It accepts input voltages from 4.5 VDC to 65 VDC and delivers up to 1-A average LED current with ±3% accuracy.
Key features include up to 96% efficiency, integrated low-side N-channel MOSFET, and no external current sensing resistor required. The device supports adjustable constant LED current from 350 mA to 1000 mA, analog dimming, and thermal fold-back functions. The switching frequency is adjustable from 250 kHz to 1000 kHz, easing EMI concerns.
This LED driver is suitable for driving single strings of high-brightness LEDs and is available in SOIC-8 and 3 mm × 3 mm WSON-8 packages. Its design is optimized for applications such as architectural lighting, office troffers, and automotive lighting.
The LM3414HV offers thermal shutdown protection and a high contrast ratio due to its minimum dimming current pulse width of less than 10 µS. It requires no external loop compensation network, simplifying circuit design.
