ISL6745 Summary of contents
Page 1
... 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. ...

... Functional Description Features The ISL6745 PWM is an excellent choice for low cost bridge topologies for applications requiring accurate frequency and deadtime control. Among its many features are 1A FET drivers, adjustable soft-start, overcurrent protection and internal thermal protection, allowing a highly flexible design with minimal external components ...

... The soft-start voltage is clamped to 4V. Gate Drive The ISL6745 is capable of sourcing and sinking 1A peak current, and may also be used in conjunction with a MOSFET driver such as the ISL6700 for level shifting. To limit the peak current through the IC, an external resistor may be placed between the totem-pole output of the IC (OUTA or OUTB pin) and the gate of the MOSFET ...
