General Description
The SIC9701 is a constant current LED regulator with high current accuracy which applies to single stage step-down power factor corrected LED drivers.
High accuracy of output current is achieved by sampling the output current directly.Working in critical conduction mode operation reduces the switching losses and largely increases the efficiency.
The SIC9701 is supplied from the output directly, and auxiliary winding is not needed.
The SIC9701 has multi-protection functions which largely enhance the safety and reliability of the system, including VDD over-voltage protection, VDD UVLO, short-circuit protection, LED open protection, cycle-by-cycle current limit and over-temperature protection.
The SIC9701 available in Compact SOT23-6 package.
