Overview: ISL6745 NOT REMENDED FOR NEW DESIGNS REMENDED REPLACEMENT PART ISL6745A Bridge Controller with Precision Dead Time Control DATASHEET
FN9161 Rev.6.00 Sept 1, 2005 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 nonoverlap time (“deadtime”) with deadtimes as low as 35ns, allowing power engineers to optimize the efficiency of openloop bus converters. The ISL6745 also includes a control voltage input for closed-loop PWM and line voltage feedforward functions.
Low start-up and operating currents allow for easy biasing in both AC/DC and DC/DC applications.
