NCP4306 Synchronous Rectification Drivers

onsemi NCP4306 Synchronous Rectification Drivers are high‑performance secondary‑side devices designed to optimize efficiency in switch‑mode power supplies (SMPS). The onsemi NCP4306 supports a wide range of power‑conversion topologies (including DCM/CCM flyback, quasi‑resonant flyback, forward, and resonant LLC) thanks to the versatile control architecture and robust drive capability. These devices provide precise true secondary‑side zero‑current detection and offer extremely low turn‑off delay (typically 15ns), enabling maximum MOSFET conduction time and improved overall system efficiency. The combination of adjustable or fixed minimum on‑time and off‑time blanking allows designers to mitigate PCB‑induced ringing and parasitic effects for stable, noise‑free SR operation.
