LED driver ICs control the brightness of LED bulbs and the stability of images on LED displays. Littelfuse makes two types of these specialized integrated circuits. While relying on different gate drivers, each delivers high efficiency with low power consumption and low unit costs. Each can also be used as a dimmer. To learn which IC provides the best solution for your application, consult out Integrated Circuits Selection Guide.
- Operate at wide ranges of input voltage (e.g., 8 V dc to 550 V dc)
- Employ power factor correction technology
- Low-profile designs (e.g., 6x1.27 mm pin-to-pin)
- Certified lead-free and RoHS compliant
- Can be used as dimmers
- Provide supplemental overcurrent, overvoltage, and overtemperature protection
- 8-pin designs simplify IC design by dedicating each pin to a prescribed input or output
- Convert at least 90% of power input to signal
- Proven to hold brightness levels and images steady through low-level transient current and voltage surges
