An LED Driver IC is an integrated circuit designed to control the operation of light-emitting diodes (LEDs). These components manage the power supply to LEDs, ensuring they operate efficiently and effectively. LED Driver ICs can be configured for various applications, providing features such as constant current regulation, dimming control, and thermal management.
| Input voltage range | 3V to 60V |
| Output current range | 20mA to 1A |
| Efficiency | Up to 95% |
| Package types | SMD, DIP, QFN |
| Control methods | PWM, analog dimming |
| Operating temperature range | -40°C to 125°C |
When selecting an LED Driver IC, consider the input voltage and output current requirements of your LED application. It's important to specify the desired efficiency and control method, such as PWM or analog dimming. Additionally, check for thermal management features and ensure the IC operates within the required temperature range. Certifications may be relevant depending on the application, so inquire about any necessary compliance standards.
