Improved Indus try Standard Single Ended  
Current Mode PWM Controller  
Features  
• 1A MOSFET gate driver  
The ISL6842, ISL6843, ISL6844, ISL6845 family of  
adjustable frequency, low power, pulse width modulating  
(PWM) current mode controllers is designed for a wide range  
of power conversion applications including boost, flyback,  
and isolated output configurations. Peak current mode  
control effectively handles power transients and provides  
inherent over-current protection.  
• 60µA startup current, 100µA maximum  
• 30ns propagation delay current sense to output  
• Fast transient response with peak current mode control  
• Adjustable switching frequency to 2MHz  
• 20ns rise and fall times with 1nF output load  
This advanced BiCMOS design is pin compatible with the  
industry standard 384x family of controllers and offers  
significantly improved performance. Features include low  
operating current, 60µA 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  
• High bandwidth error amplifier  
• Tight tolerance voltage reference over line, load, and  
temperature  
• Tight tolerance current limit threshold
