Improved Bridge Controller with Precision Dead Time Control

Description

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 (dead time) with dead times 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 10 Ld MSOP package and is assured to meet rated specifications across a wide -40 °C to +105 °C temperature range.
