ISL6744
FN9147.8
Intermediate Bus PWM Controller
The ISL6744 is a low cost, primary side, double-ended
controller intended for applications using full and half-bridge
topologies for unregulated DC/DC converters. It is a voltage-
mode PWM controller designed for half-bridge and full-
bridge power supplies. It provides precise control of
switching frequency, adjustable soft-start, precise deadtime
control with deadtimes as low as 35ns, and overcurrent
shutdown.
Low start-up and operating currents allow for easy biasing in
both AC/DC and DC/DC applications. This advanced
BiCMOS design features low start-up and operating
currents, adjustable switching frequency up to 1MHz, 1A
FET drivers, and very low propagation delays for a fast
response to overcurrent faults.

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.
