ISL6745
Bridge Controller with Precision Dead
Time Control
The ISL6745 is a low-cost double-ended voltage-mode
PWM controller designed for half-bridge and full-bridge
power supplies and line-regulated bus converters. It
provides precise control of switching frequency, adjustable
soft-start, and overcurrent shutdown. In addition, the
ISL6745 allows for accurate adjustment of MOSFET non-
overlap time (“deadtime”) with deadtimes as low as 35ns,
allowing power engineers to optimize the efficiency of open-
loop bus converters. The ISL6745 also includes a control
voltage input for closed-loop PWM and line voltage feed-
forward functions.
Low start-up and operating currents allow for easy biasing in
both AC/DC and DC/DC applications. This advanced
BiCMOS design also features adjustable switching
frequency up to 1MHz, 1A FET drivers, and very low
propagation delays for a fast response to overcurrent faults.
The ISL6745 is available in a space-saving MSOP-10
package and is guaranteed to meet rated specifications over
a wide -40°C to 105°C temperature range.

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.
