描述

The ISL6726 is a highly featured single-ended PWM controller intended for applications using the active clamp forward converter topology in either n- or p-channel active clamp configurations, the asymmetric half-bridge topology, and the standard forward topologies with synchronous rectification. It is a current-mode PWM controller with many features designed to simplify its use. Among its many features are a precision oscillator which allows accurate control of the deadtime and maximum duty cycle, bi-directional synchronization with 180° phase shift for interleaving applications, adjustable soft-start and soft-stop, a low power disable mode, and average current limit for brick-wall overcurrent protection. This advanced BiCMOS design features low start-up and operating currents, adjustable switching frequency to greater than 1MHz, high current FET drivers, and very low propagation delays for a fast response to overcurrent faults.
