The BP2833D is an LED driver IC designed for high-efficiency, low-cost LED lighting applications. Below are its key specifications, descriptions, and features:

Manufacturer:

BP (Bright Power Semiconductor)

Specifications:

• Input Voltage Range: 85V–265V AC (universal input)
• Output Power: Up to 18W
• Output Current: Adjustable (typically 300mA–600mA)
• Switching Frequency: ~50kHz (fixed)
• Efficiency: Up to 85%
• Operating Temperature: -40°C to +105°C
• Package: SOP-8 (Surface Mount)
• Protections:
• Over-temperature protection (OTP)
• Over-voltage protection (OVP)
• LED open/short-circuit protection

Description:

The BP2833D is a primary-side regulation (PSR) LED driver IC, eliminating the need for an optocoupler or secondary feedback circuit. It integrates a high-voltage power MOSFET and provides constant current (CC) output for LED lighting. It is commonly used in LED bulbs, tubes, and downlights.

Features:

• Primary-Side Control: No secondary feedback required.
• High PF (Power Factor): >0.9 (meets energy efficiency standards).
• Low THD (Total Harmonic Distortion): <20%.
• Built-in MOSFET: Reduces external component count.
• Precision Current Control: ±5% accuracy.
• Dimmable (Optional): Compatible with TRIAC dimmers (with external circuitry).
• Low Standby Power: <0.3W.

This IC is widely used in non-isolated LED drivers for cost-sensitive lighting applications.
