synchronous rectifier controller

eGaN ® FET-based power conversion systems offer higher efficiency, increased power density, and lower overall system cost than Si-based alternatives. The synchronous rectifier controller may determine whether to adjust the reference signal used by the synchronous rectifier controller to turn off the synchronous rectifier during subsequent switching cycles. Due to the fact that synchronous rectifiers are active devices, the design and utilization of synchronous rectification need to be properly addressed.

The SR drive circuit is a discrete voltage-based controller. nSmall SO-8 Package The LTC®3900 is a secondary-side synchronous recti- fier driver designed to be used in isolated forward con- verter power supplies. Perhaps more problematic is that in DCM, the control IC isn’t necessarily ‘aware’ that the stored energy has all been transferred. When the synchronous rectifier controller is disabled, the body diode of the synchronous rectifier begins to conduct resulting in higher conduction losses and thermal issues.

ON Semiconductor has introduced an advanced synchronous rectifier (SR) controller optimized for LLC resonant converter topologies. It provides two high current gate drive outputs, each capable of driving one or more N-channel power MOSFETs. Many of today’s switching power supplies implement synchronous rectifiers to improve efficiency. ON Semiconductor FAN6240 Synchronous Rectifier Controller is a secondary-side synchronous rectifier (SR) controller for an isolated flyback converter operating in Discontinuous Conduction Mode (DCM). These advantageous characteristics have spurred the presence of an ever increasing ecosystem of power electronics components such as gate drivers, controllers, and passive components that specifically enhance eGaN FET performance. The synchronous rectifier driver is the IR1176, a new member of a family of controllers. Thus, synchronous rectification is unavailable across the entire operating range of the constant current mode in conventional switched mode power supplies. Unlike prior solutions that used a signal transformer driven from the primary side to control the synchronous rectifier, our solutions sense the drain-to-source voltage of the MOSFET for activation. In isolated topologies, the power-supply controller typically is located on the primary side of the isolation barrier, while the synchronous rectifiers are located on the secondary side. Power Management. Synchronous Rectifier Controller The NCP43080 is a synchronous rectifier controller for switch mode power supplies. Synchronous rectification switchers and controllers improve efficiency over classical rectifiers.
