Radiation Hardened, High Performance Industry  
Standard Single-Ended Current Mode PWM  
Controller  
ISL78840ASRH, ISL78841ASRH, ISL78843ASRH, ISL78845ASRH  
The ISL7884xASRH is a high performance, radiation  
hardened drop-in replacement for the popular 28C4x and  
Features  
• Electrically Screened to DSCC SMD # 5962-07249  
• QML Qualified Per MIL-PRF-38535 Requirements  
• 1A MOSFET Gate Driver  
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  
Features include up to 13.2V operation, low operating  
current, 90µA typ start-up current, adjustable operating  
frequency to 1MHz, and high peak current drive  
capability with 50ns rise and fall times.  
• Fast Transient Response with Peak Current Mode  
Control  
• 9V to 13.2V Operation  
• Adjustable Switching Frequency to 1MHz  
• 50ns Rise and Fall Times with 1nF Output Load
