概述
Description
NCL30082BDR2G is an ON Semiconductor LED driver IC. It is an off-line flyback switching regulator with an integrated high-voltage power MOSFET, designed to drive constant-current LED strings directly from rectified mains in compact LED lighting applications.
Key points:
- Integrated high-voltage FET and current-mode control for simple, few-external-part LED drivers.
- Primary-side regulation and/or sense-feedback configurations to regulate LED current.
- Protections: open/short LED protection, overcurrent/overvoltage protection, and thermal shutdown.
- Soft-start and dimming support (PWM or analog dimming interfaces) for brightness control.
- Packaged in the BDR2G designation (a small, high-density package).
Typical uses include LED bulbs, downlights, and signage where offline, constant-current LED driving is desired with minimal external components. For exact electrical specs (LED current level, input range, dimming behavior, soft-start, and protection thresholds), refer to the NCL30082BDR2G datasheet and product page.
