The ISL884xA 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, 90μA

start-up current, adjustable operating frequency to 2MHz,

and high peak current drive capability with 20ns rise and fall

times.

Features

? 1A MOSFET gate driver

? 90μA start-up current, 125μA maximum

? 35ns propagation delay current sense to output

? Fast transient response with peak current mode control

? 30V operation

? Adjustable switching frequency to 2MHz

? 20ns rise and fall times with 1nF output load

? Trimmed timing capacitor discharge current for accurate

deadtime/maximum duty cycle control

? 1.5MHz bandwidth error amplifier

? Tight tolerance voltage reference over line, load and

temperature

? ±3 current limit threshold

? Pb-free plus anneal available and ELV, WEEE, RoHS

Compliant

Applications

? Telecom and datacom power

? Wireless base station power

? File server power

? Industrial power systems

? PC power supplies

? Isolated buck and flyback regulators

? Boost regulators
