    Mode PWM Controller
    The ISL78840ASEH, ISL78841ASEH, ISL78843ASEH,
    ISL78845ASEH, ISL78840ASRH, ISL78841ASRH,
    ISL78843ASRH, ISL78845ASRH are a high performance,
    radiation hardened 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 up to 13.2V operation, low operating current,
    90ВµA typical start-up current, adjustable operating frequency
    to 1MHz and high peak current drive capability with 50ns rise
    and fall times. Applications Features Electrically screened to DLA SMD #5962-07249 QML Qualified Per MIL-PRF-38535 Requirements 1A MOSFET Gate Driver 90ВµA typical start-up current, 125ВµA Maximum 35ns propagation delay current sense to output Fast transient response with peak current mode control 9V to 13.2V operation Adjustable switching frequency to 1MHz 50ns rise and fall times with 1nF output load Trimmed timing capacitor discharge current for accurate
    deadtime/maximum duty cycle control Current mode switching power supplies 1.5MHz bandwidth error amplifier Isolated buck and flyback regulators Boost regulators Tight tolerance voltage reference over line, load and
