Комментарии об отличиях

SM2082 ↔ BP2833

SM2082: linear LED driver IC, constant current 5-60mA, 500V, SOP-8, для non-isolated applications. BP2833: non-isolated buck offline LED driver, 85-265VAC universal input, 500V internal MOSFET, critical conduction mode (CRM), ±5% output current accuracy, no auxiliary winding, SOP-8. ОТЛИЧИЯ: (1) SM2082 — LINEAR driver ( dissipates excess voltage), BP2833 — BUCK switching driver (higher efficiency 85-90%); (2) BP2833 имеет active PFC неявно через CRM; (3) разная обвязка: SM2082 — resistor + LED string, BP2833 — inductor + diode + CS resistor (full buck topology). Это НЕ pin-to-pin функционально, хотя корпус тот же. Требуется адаптация обвязки.
