Data Sheet

FN6797.0  
Flexible Single-ended Current Mode PWM  
Controller  
Features  
• 1A MOSFET Gate Driver  
• 100µA Startup Current  
The ISL6721A is a low power, single-ended pulse width  
modulating (PWM) current mode controller designed for a  
wide range of DC/DC conversion applications including  
boost, flyback, and isolated output configurations. Peak  
current mode control effectively handles power transients  
and provides inherent overcurrent protection. Other features  
include a low power mode where the supply current drops to  
less than 200µA during overvoltage and overcurrent  
shutdown faults. It differs from the ISL6721 in that the UVLO  
and UV thresholds have been modified.  
• Fast Transient Response with Peak Current Mode Control  
• Adjustable Switching Frequency up to 1MHz  
• Bidirectional Synchronization  
• Low Power Disable Mode  
• Delayed Restart from OV and OC Shutdown Faults  
• Adjustable Slope Compensation  
• Adjustable Soft-start  
This advanced BiCMOS design features low operating  
current, adjustable operating frequency up to 1MHz,  
adjustable soft-start, and a bidirectional SYNC signal that  
allows the oscillator to be locked to an external clock for  
noise sensitive applications.  
• Adjustable Overcurrent Shutdown Delay  
• Adjustable UV and OV Monitors  
• Leading Edge Blanking  
• Integrated Thermal Shutdown  
Applications  
• 1% Tolerance Voltage Reference  
• Pb-Free (RoHS Compliant)  
Telecom and Datacom Power  
• Wireless Base Station Power  
• File Server Power  
• Industrial Power Systems  
• Isolated Buck and Flyback Regulators  
• Boost Regulators
