Overview
NCP43080 Synchronous Rectifier Controller The NCP43080 is a synchronous rectifier controller for switch mode power supplies.
The controller enables high efficiency designs for flyback and quasi resonant flyback topologies.
Externally adjustable minimum off−time and on−time blanking periods provides flexibility to drive various MOSFET package types and PCB layout.
A reliable and noise less operation of the SR system is insured due to the Self Synchronization feature.
The NCP43080 also utilizes Kelvin connection of the driver to the MOSFET to achieve high efficiency operation at full load and utilizes a light load detection architecture to achieve high efficiency at light load.
The precise turn−off threshold, extremely low turn−off delay time and high sink current capability of the driver allow the maximum synchronous rectification MOSFET conduction time.
The high accuracy driver and 5 V gate clamp make it ideally suited for directly driving GaN devices.
