AR30N60

Description

The AR30N60 is a high-performance Active/Synchronous Rectifier used for secondary-side synchronous rectification with the output voltage at less than 10V.

By integrating MOSFET and controller, the AR30N60 emulates the characteristics of a near-ideal diode rectifier. The combination not only reduces the energy consumption of the secondary-side synchronous rectifier, it also improves the power dissipation of the sub-system on the primary side.

The SYNC feature allows the embedded MOSFET of the AR30N60 to immediately turn OFF as soon as the primary-side switch turns ON, preventing the unfavorable reverse condition of the synchronous rectifier. The AR30N60 is ideally suited for AC/DC power converters implemented in either the flyback or the LLC-resonant topology. For the ease of use, the design of AR30N60 is flexible enough to facilitate operation in one of the following modes: Discontinuous Conduction (DCM), Continuous Conduction (CCM), Quasi Resonant (QR).

To further improve conversion efficiency and to ensure system integrity, AR30N60 integrates many innovative features. These include: light-load detection to reduce standby power consumption, T_ON and T_OFF/EN pins to prevent run-away ON-time due to the open-circuit or short-circuit fault conditions, SFB pin to provide overtemperature protection, low R_DS(ON) of the embedded MOSFET, and wide output voltage (V_CC) range.

The small footprint of the V-DFN6040-22 package makes it ideally suited for space constrained applications.
