The ISL78840ASEH, ISL78841ASEH, ISL78843ASEH, ISL78845ASEH, ISL78840ASRH, ISL78841ASRH, ISL78843ASRH, ISL78845ASRH are high-performance, radiation hardened drop-in replacements for the popular 28C4x and 18C4x PWM controllers suitable for a wide range of power conversion applications including boost, flyback and isolated output configurations. Fast signal propagation and output switching characteristics make these ideal products for existing and new designs. Features include up to 13.2V operation, low operating current, 90μA typical start-up current, adjustable operating frequency to 1MHz, and high peak current drive capability with 50ns rise and fall times.
