LED driver ICs supply constant-current or constant-voltage drive to LED loads for lighting, display backlighting and indicators, with the core task of keeping LED brightness stable across temperature and voltage variation.
- Output current accuracy and linear dimming capability determine brightness uniformity across parallel/series LED strings
- Dimming method (PWM/analog) and dimming ratio range affect low-brightness display quality
- Efficiency and thermal design matter especially in high-current drive applications with rising junction temperature
- Protection completeness (open/short-circuit detection) affects system safety on LED-string failure
