    April 18, 2007 High Performance Industry Standard Single-Ended Current Mode PWM Controller The ISL884xA is a high performance drop-in replacement for
    the popular 28C4x and 18C4x PWM controllers suitable for a
    wide range of power conversion applications including
    boost, flyback, and isolated output configurations. Its fast
    signal propagation and output switching characteristics
    make this an ideal product for existing and new designs.
    Features include 30V operation, low operating current, 90A
    start-up current, adjustable operating frequency to 2MHz,
    and high peak current drive capability with 20ns rise and fall
    times. Features 1A MOSFET gate driver 90A start-up current, 125A maximum 35ns propagation delay current sense to output Fast transient response with peak current mode control 30V operation Adjustable switching frequency to 2MHz 20ns rise and fall times with 1nF output load PART NUMBER RISING UVLO MAX.
