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
