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.
