General Description
The SIC9521/SIC9522 are high precision Non-Isolation LED drivers for buck LED lighting application. They are suited AC 85V-265V non-isolated LED driver supply Typical ± 5% Output current accuracy achieved by built-in high precision sampling and compensation circuit.Integrated 500V power MOSFET, without secondary feedback circuit, also need not compensation circuit, the drivers have good performance with very simple peripheral circuits.
The SIC9521/SIC9522 have multi-protection functions which largely enhance the safety and reliability of the system, including VCC over-voltage protection, VCC UVLO, short-circuit protection, cycle-by-cycle current limit and over-temperature protection.
The SIC9521/SIC9522 are available in compact TO-94 package.
