Product Specification

SIC9752/SIC9753/SIC9754

General Description

The SIC9752/SIC9753/SIC9754 are constant current LED regulators with high current accuracy

which applies to single stage step-down power factor corrected LED drivers. 600V power

MOSFET is integrated, which can significantly simplify the design of LED lighting system.

High accuracy of output current is achieved by sampling the output current directly. Critical

conduction mode operation reduces the switching losses and largely increases the efficiency.

The SIC9752/SIC9753/SIC9754 is supplied from the output directly, and auxiliary winding is not

needed.The SIC9752/SIC9753/SIC9754 has multi-protection functions which largely enhance the

safety and reliability of the system, including V_DDover-voltage protection, V_DDUVLO,

short-circuit protection, LED open protection, cycle-by-cycle current limit and over-temperature

protection.

The SIC9752/SIC9753/SIC9754 available in SOP-8 & DIP-7 packages.
