ISL6721
Flexible Single Ended Current Mode PWM
Controller
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.
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.

reel specifications.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.
