Keep leakage inductance below 3% of the primary inductance to prevent voltage spikes from triggering the OVP pin prematurely.

The LZC8650C belongs to a family of LED driver ICs (like the DIO8650C and LZC8620 ) that focus on efficiency and power quality.

💡 The LZC8650C is frequently used in 45W to 110W LED drivers, often paired with high-voltage MOSFETs like the 8N70. Datasheet Links

A superior datasheet is digitally created, meaning you can Ctrl+F to find terms like “efficiency,” “inductor,” or “ESR.” Scanned PDFs are frustrating and error-prone.
