AR30N60
Description
ACTIVE / SYNCHRONOUS RECTIFIER
Pin Assignments
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,
TON and TOFF/EN pins to prevent run-away ON-time due to the open-
circuit or short-circuit fault conditions, SFB pin to provide over-
temperature protection, low RDS(ON) of the embedded MOSFET, and
wide output voltage (VCC) range.
The small footprint of the V-DFN6040-22 package makes it ideally
suited for space constrained applications.

Steps of Operation
(1) At the logic „H‟ of the internal signal ARM, the voltage level of VDS shall be checked continuously. At this time, no current should flow through
the embedded MOSFET (neither its body-diode).
(2) When the primary-side controller stops conducting, the transfer of energy to the secondary-side commences. At this time, the current flowing
through the body-diode of embedded MOSFET shall rise rapidly. When VDS ≤ VTHON (-130mV typical), the embedded MOSFET is turned ON,
the TON timer starts decrementing, and the ARM signal is reset. Before the TON timer expires, the embedded MOSFET shall remain ON.
(3) Now, the TON timer expires. If VDS is still lower than VTHOFF, the embedded MOSFET shall remain ON.
(4) Eventually, the current flowing through the embedded MOSFET falls to zero. Once VDS ≈ VTHOFF, the embedded MOSFET shall be turned
OFF.
(5) Because the ARM signal remains at the OFF state, the embedded MOSFET is kept at the OFF state even if VDS ≤ VTHON. That is, the value of
VDS is ignored.
(6) The primary-side controller starts conducting. This causes the signal at the input of the SYNC pin to be pulled down. As soon as the condition
[VSYNC < (VAVDD – 2V)] becomes true, the TOFF timer starts decrementing.
(7) After the TOFF timer expires, the AR30N60 starts to monitor the voltage level of VDS as soon as the ARM signal becomes „H‟.
