• Smart Turn off Technology
• Secondary-side Synchronous Rectifier for 5V~12V Systems
• Suitable for Discontinuous Mode (DCM), Critical Conduction Mode (CRM)
• Suitable for Primary Side Regulation (PSR), Secondary Side Regulation (SSR)
• Compact Package: SOT335 

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.
