    3 Description



    The LM3429 is a versatile high voltage N-channel
    MosFET controller for LED drivers. It can beeasily
    configured in buck.boostbuck-boost and SEPIC
    topologies. This flexibility, along with an input voltage
    rating of 75Vmakes the LM3429 ideal for
    illuminating LEDs in a very diverse large family of
    applications.
    Adjustable high-side current sense voltage allows for
    liaht requlation of the LED current with the highes
    efficiency possible. The LM3429 uses Predictive Off
    time (PRO) control. which is a combination ofpeak
    current-mode control and a predictive off-timer.This
    method of control eases the design ofloop
    compensation while providing inherent input voltage
    feed-forward compensation.
    The LM3429 includes a high-voltage startup regulator
    that operates over a wide inout range of45vto75
    V. The intenal PwM controller is designed for
    adjustable switching frequencies of up to2 MHzthus
    enabling compact solutions.Additionalfeatures
    include analog dimming,PWMdimmingovervoltage
    protection.undervoltage lock-outcycle-by-cycle
    current limit. and thermal shutdown.
