Linear drivers (simple, low EMI, heat dissipation), buck drivers (efficient for high input), boost drivers (for series LEDs), and AC-DC offline drivers for mains lighting.
Output current accuracy, dimming method (PWM/analog), efficiency, PF (power factor) for mains, and thermal package. Choose constant-current drivers for consistent light output.
Indoor/outdoor lighting, backlighting, automotive lighting, signage and horticultural lighting each require specific driver families.
LED driver ICs from TI, MPS, Infineon and domestic makers have strong supply. HuaXinGou quotes common families (e.g., PT4115, AL8861, TPS61165) with alternatives.
