Description

Support is limited to customers who have already adopted these products.

The ISL8843 is an industry standard drop-in replacement for the popular 28C43 and 18C43 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 30V operation, low operating current, 90µA start-up current, adjustable operating frequency to 2MHz, and high peak current drive capability with 20ns rise and fall times.
