The SD6921S LED driver SOP7 RoHS is a 7-pin semiconductor chip manufactured by Silan. It is designed to be used as a switch-mode current regulator for driving small light emitting diodes (LEDs). The driver can support up to 2A of continuous current and features a wide voltage range of up to 32V. The chip includes an adjustable soft-start to reduce in-rush current, and incorporates a power loss circuit to protect LEDs from over-current. It also has an over-temperature protection and a shutdown mode. Applications for this driver include LED backlights, LED signage, automotive lighting, and more. The driver is compliant with IEC, JEDEC, and RoHS standards.
