Flexible Single Ended Current Mode PWM

Controller

Features

• 1A MOSFET Gate Driver

The ISL6721 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.

• 100μA Startup Current

• Fast Transient Response with Peak Current Mode Control

• Adjustable Switching Frequency up to 1MHz

• Bi-Directional Synchronization

• Low Power Disable Mode

• Delayed Restart from OV and OC Shutdown Faults

• Adjustable Slope Compensation

This advanced BiCMOS design features low operating

current, adjustable operating frequency up to 1MHz,

adjustable soft-start, and a bi-directional SYNC signal that

allows the oscillator to be locked to an external clock for

noise sensitive applications.

• Adjustable Soft-start

• Adjustable Overcurrent Shutdown Delay

• Adjustable UV and OV Monitors

• Leading Edge Blanking

Ordering Information

• Integrated Thermal Shutdown

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
