NCL30082BDR2G

Introduction to NCL30082BDR2G
- What it is: An off-line flyback controller IC from ON Semiconductor used for constant-current LED drivers and similar standalone power supplies.
- Topology: Primary-side control for a flyback converter. Typically requires an external power MOSFET and a transformer; no optocoupler is needed if you use primary-side regulation.
- Key features: High-voltage startup, current-mode control, fixed (or stable) switching frequency, and efficiency-boosting techniques (often valley switching). Includes primary-side regulation options and protection features.
- Protections: Overcurrent/short-circuit protection, overvoltage protection, thermal shutdown, and other fault protections to improve reliability.
- Dimming: Supports dimming options (e.g., PWM or DC dimming inputs) to control LED output.
- Package variant: NCL30082BDR2G specifies a particular RoHS-compliant package/version from ON Semiconductor.
- Typical applications: Small to mid-size LED drivers, adapters, standby or auxiliary supplies requiring isolated, constant-current output.
If you want, I can pull out exact electrical specs (input range, output current range, startup current, and typical operating frequency) from the datasheet.

Key features of NCL30082BDR2G (concise):
- Offline, constant-current LED driver with primary-side regulation (PSR) – no opto-isolator needed
- Integrated high-voltage switch/MOSFET
- Universal input: wide AC range (85–265 VAC)
- Fixed-frequency, current-mode (valley-current) control
- Protection: hiccup for overload/short, overcurrent, overvoltage, and thermal shutdown
- PWM/dimming interface support
- Small 8-pin package (BDR2G), RoHS-compliant
- High efficiency and compact solution for driving LED strings in lighting applications
Note: exact electrical specs (current range, startup values, etc.) are per datasheet revision and configuration.

NCL30082BDR2G comes in an 8-pin MSOP package (MSOP-8), RoHS-compliant.

- Pin count: 8 pins (8-pin package).
- Function: High-side constant-current LED driver/controller (buck regulator) for driving LED strings. It uses a sense resistor and feedback to regulate LED current, with EN and DIM inputs for enable/dimming and typical protection features.
