  • Description
    JW®1237A, integrated with 60V NMOSFET, is used to drive a LED string, and remove the 100/120Hz LED current ripple on AC/DC power by a capacitor between VC and GND.
    The adaptive technology ensures minimum power dissipation on JW1237A while removing LED current ripple.
    Specially designed algorithms support the good compatibility for dimming and electronic load applications. The adaptive technics of JW1237A ensure minimum power dissipation while removing LED current ripple.
    JW1237A allows user to setup maximum LED current, which protects NMOSFET from being damaged when LED short connected or hot-plug.
    JW1237A also allows users to setup the maximum cathode voltage of LED string, which could help limit the power dissipation on chip. 
    JW1237A has multi-protection functions which largely enhance the safety and reliability of the system, including VIN UVLO, short-circuit protection, LED open protection, and over temperature protection.
