The SY23429A is a high-performance synchronous rectifier which contains controller and MOSFET devices. This solution not only directly reduces power dissipation of the rectifier but also indirectly reduces primary-side losses, due to compounding of efficiency gains. The DRAIN pin of SY23429A can support 60V voltage stress.
The SY23429A will achieve ultra-low power consumption when the circuit operates in no load.
The SY23429A is available in a compact SOT335 package.
