    ISL8843 FN9238
    Rev 2.00
    September 14, 2015 Industry Standard Single-Ended Current Mode PWM Controller
    The ISL8843 is an industry standard drop-in replacement for
    the popular 28C43 and 18C43 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.
    PART NUMBER RISING UVLO MAX. DUTY CYCLE ISL8843 8.4V 100% 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 Trimmed timing capacitor discharge current for accurate
    deadtime/maximum duty cycle control 1.5MHz bandwidth error amplifier Ordering Information
