Rev 3.00  
April 18, 2007  
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  
Features  
• 1A MOSFET gate driver  
boost, flyback, and isolated output configurations. Its fast  
signal propagation and output switching characteristics  
make this an ideal product for existing and new designs.  
• 90A start-up current, 125A maximum  
• 35ns propagation delay current sense to output  
• Fast transient response with peak current mode control  
• 30V operation  
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.  
• Adjustable switching frequency to 2MHz  
• 20ns rise and fall times with 1nF output load
