The ISL6745A 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
ISL6745A 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 ISL6745A also includes a
control voltage input for closed-loop PWM and line voltage
feed-forward functions. The ISL6745A is identical to the
ISL6745, but is optimized for higher noise environments.
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 ISL6745A 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.
