Enhanced Plastic (EP) High Performance
Industry Standard Single-Ended Current
Mode PWM Controllers
The ISL884xAMBEP 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 flyback, forward and boost 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, 90
μ
A
start-up current, adjustable operating frequency to 2MHz,
and high peak current drive capability with 20ns rise and fall
times.
Device Information
The specifications for an Extended Plastic (EP) device are
defined in a Vendor Item Drawing (VID), which is controlled
by the Defense Supply Center in Columbus (DSCC). “Hot-
links” to the applicable VID and other supporting application
information are provided on our website.
