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碌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.

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.
