High Performance Industry Standard Single-Ended Current Mode PWM Controller

The ISL8840A ISL8841A ISL8842A ISL8843A ISL8844A ISL8845A is a high performance 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 30V operation, low operating current, 90A start-up current, adjustable operating frequency to 2MHz, and high peak current drive capability with 20ns rise and fall times.
