    August 5, 2016 Radiation Hardened High-Speed, Dual Output PWM
    The radiation hardened HS-1825ARH, HS-1825AEH pulse
    width modulator is designed to be used in high frequency
    switched-mode power supplies and can be used in either
    current-mode or voltage-mode. It is well suited for single-ended
    boost converter applications.
    Device features include a precision voltage reference, low
    power start-up circuit, high frequency oscillator, wide-band
    error amplifier and fast current-limit comparator. The use of
    proprietary process capabilities and unique design techniques
    results in fast propagation delay times and high output current
    over a wide range of output voltages.
    Constructed with the Intersil radiation hardened Silicon Gate
    (RSG) Dielectric Isolation BiCMOS process, the HS-1825ARH,
    HS-1825AEH have been specifically designed to provide highly
    reliable performance when exposed to harsh radiation
    environments. Features Electrically screened to DLA SMD # 5962-99558 QML qualified per MIL-PRF-38535 Requirements Radiation environment
    -Maximum total dose 300 krad(SI)
