资 源 简 介

The ISL97631 represents a high efficiency, constantfrequency PWM regulator with integrated boost diode andFET. Designed for use in white LED driving applicaTIons, theISL97631 features efficiencies up to 85%. It operates at1.35MHz switching frequency and operates from an inputvoltage of between 2.7V and 5.5V. The maximum outputvoltage of 27V enables the ISL97631 to drive up to 6 LEDs inseries. It is also possible to use the ISL97631 to drive LEDsin series/parallel combinaTIon for applicaTIons requiring up to15 LEDs.Available in the 6 Ld TSOT package, the ISL97631 offershigh efficiency, constant frequency operaTIon. It is specifiedfor operation over the -40°C to +85°C ambient temperaturerange.
