Flexible Single Ended Current Mode PWM
Controllers
The ISL6722A and the ISL6723A are low power, single-
ended pulse width modulating (PWM) current mode
controllers designed for a wide range of DC/DC conversion
applications including boost, flyback, and isolated output
configurations. Similar to, and pin compatible with the
ISL6721, the ISL6722A and ISL6723A offer a modified
feature set. The ISL6722A replaces external synchronization
with a low power SLEEP feature that reduces standby
current to under 200碌A. The ISL6723A changes the supply
voltage UVLO threshold to 13V. Additionally, the internal
over temperature protection has been removed in both
controllers. Other features remain the same and include a
low power mode during overvoltage and overcurrent
shutdown faults where the supply current drops to 200碌A.
An internal 300ms delay timer prevents rapid 鈥渉iccup鈥?/div>
behavior when a shutdown fault does occur.
This advanced BiCMOS design features low operating
current, adjustable operating frequency up to 1MHz, and
adjustable soft-start.

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.
