The ISL6740IB-T is a low power, adjustable frequency Pulse Width Modulating (PWM) voltage mode controller designed for various power conversion applications, including half-bridge, full bridge, and push-pull configurations. It features an adjustable switching frequency of up to 1MHz, precision control of duty cycle and dead time, and a low start-up current of 95µA. The controller includes adjustable soft-start, internal and external over-temperature protection, and fault annunciation capabilities. It also supports bidirectional synchronization, allowing it to be locked to paralleled units or an external clock, which is beneficial for noise-sensitive applications. The ISL6740IB-T is suitable for use in telecom and datacom power systems, wireless base stations, file servers, and industrial power systems. It is RoHS compliant and available in a 16-lead TSSOP package.
