Datasheet  
ISL6840, ISL6841, ISL6842, ISL6843, ISL6844  
Improved Industry Standard Single-Ended Current Mode PWM Controller  
The ISL6840, ISL6841, ISL6842, ISL6843, and  
ISL6844 (ISL684x) family of adjustable frequency, low  
power, Pulse-Width Modulating (PWM) current mode  
Features  
• 1A MOSFET gate driver  
• 60µA start-up current, 100µA maximum  
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 overcurrent protection.  
• 25ns 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
