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 over-current protection. Other features
include a low power mode where the supply current drops to
less than 200
μ
A during over voltage and over current
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.

Add “-T” suffix to part number for tape and reel packaging.
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
