The ISL6844IB is a single-ended current mode PWM controller designed for various power conversion applications, including isolated buck and flyback regulators, as well as boost regulators. It features a 1A MOSFET gate driver and operates with a low start-up current of 60µA, making it suitable for energy-efficient designs. The device supports an adjustable switching frequency of up to 2MHz and offers fast transient response with a peak current mode control, which enhances its ability to handle power transients effectively. The ISL6844IB has a maximum duty cycle of 50% and a rising under-voltage lockout (UVLO) threshold of 14.4V. It is built with a high bandwidth error amplifier and provides tight tolerance on voltage reference and current limit thresholds, ensuring reliable performance across varying line, load, and temperature conditions. The product is available in a RoHS-compliant package, making it suitable for environmentally conscious applications. This controller is pin-compatible with the industry-standard 384x family, allowing for easy integration into existing designs.
