DATASHEET ISL6740, ISL6741 FN9111 Rev.7.00 Flexible Double Ended Voltage and Current Mode PWM Controllers Jul 7, 2017 The ISL6740, ISL6741 family of adjustable frequency, low Features power, Pulse Width Modulating (PWM) voltage mode Precision duty cycle and dead time control (ISL6740) and current mode (ISL6741) controllers, is designed for a wide range of power conversion applications using 95A start-up current half-bridge, full bridge and push-pull configurations. These Adjustable delayed overcurrent shutdown and restart controllers provide an extremely flexible oscillator that allows (ISL6740) precise control of frequency, duty cycle and dead time. Adjustable short-circuit shutdown and restart This advanced BiCMOS design features low operating current, Adjustable oscillator frequency up to 2MHz adjustable switching frequency up to 1MHz, adjustable soft-start, internal and external over-temperature protection, Bidirectional synchronization fault annunciation, and a bidirectional SYNC signal that allows Inhibit signal the oscillator to be locked to paralleled units or to an external Internal over-temperature protection clock for noise sensitive applications. System over-temperature protection using a thermistor or Applications sensor Telecom and datacom power Adjustable soft-start Wireless base station power Adjustable input undervoltage lockout File server power Fault signal Industrial power systems Tight tolerance voltage reference over line, load and temperature DC transformers and bus regulators Pb-free (RoHS compliant) Related Literature ISL674x For a full list of related documents, visit our website (x =) CONTROL MODE - ISL6740, ISL6741 product pages 0Voltage Mode 1 Current Mode Ordering Information Pin Configuration ISL6740, ISL6741 PART PART TEMP.
