Intersil ISL6726单端PWM控制解决方案
Intersil公司的 ISL6726是适用于有源箝位正向转换器拓扑的单端PWM控制器，典型起动电流125uA，可调整峰值和平均限流保护，可调整软起动和软停止，具有精密的最大占空比和死区控制，内置超温保护，主要用在通信电源，AC/DC转换器以及电池充电器。本文介绍了ISL6726主要特性，方框图和典型应用电路。
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.
