High Performance Industry Standard  
Single-Ended Current Mode PWM  
Controller  
Features  
• 1A MOSFET gate driver  
• 90μA start-up current, 125μA maximum  
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.  
• 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  
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.  
• Trimmed timing capacitor discharge current for accurate  
deadtime/maximum duty cycle control  
• 1.5MHz bandwidth error amplifier
