Radiation Hardened, High Performance Industry
Standard Single-Ended Current Mode PWM Controller
ISL78840ASRH, ISL78841ASRH, ISL78843ASRH, ISL78845ASRH
The ISL7884xASRH is a high performance, radiation hardened
Features
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,
90µA typical start-up current, adjustable operating frequency
to 1MHz, and high peak current drive capability with 50ns rise
and fall times.
