一,产品概述(General Description)
      The JTM2325A/JTM2326 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 JTM2325A/JTM2326 is supplied from the output directly, and auxiliary winding is not
needed.The JTM2325A/JTM2326 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 JTM2325A/JTM2326 available in SOP-8 & DIP-7 packages.
