The ISL6742 is an advanced dual-end PWM controller with high performance, synchronous rectification control, and current limiting characteristics. It can be used in current and voltage mode control methods, and features excellent current sensing circuitry and average current limiting protection.
The ISL6742 is a high‑performance dual‑end PWM controller featuring adjustable synchronous‑rectifier control, current‑ and voltage‑mode operation, and a 2 MHz adjustable oscillator. It supports half‑bridge, full‑bridge, forward‑interleaved and push‑pull topologies and includes internal over‑temperature protection, UVLO, soft‑start and RoHS‑compliant lead‑free construction.
The document provides detailed electrical specifications, pin descriptions, typical application circuits, fault conditions, thermal protection details and design equations for current‑sharing and slope‑compensation. Package information for the 16‑lead QSOP is also included.
