Diodes' AR30N60PPA integrates the MOSFET and controller, which emulates the characteristics of a near-ideal diode rectifier. This reduces secondary-side energy consumption as well as improves primary-side power dissipation. The smart SYNC pin, when connected to a suitable primary-side control signal and under continuous conduction mode (CCM), allows the embedded MOSFET to work synchronously with the primary-side switch, thus avoiding the unfavorable shoot-through condition. Other intelligent features which improve conversion efficiency and system integrity are 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 conditions, SFB pin to provide over-temperature protection (OTP), and under-voltage lock-out (UVLO) to ensure system reliability. AR30N60PPA is ideally suited for high-efficiency AC/DC power converters which support fast charging. In addition, the device supports either flyback or LLC-resonant topology and operates under discontinuous conduction (DC), continuous conduction (CC), or quasi-resonant (QR) modes. AR30N60PPA is housed in the small form-factor DFN6040 package, which is both halogen-free and RoHS-compliant.

Features and Benefits

• Very low turn-off threshold, very small MOSFET propagation delay, and very low drain source on resistance
  
  • When operating in DC mode, the embedded AR30N60PPA MOSFET offers very low turn-off threshold (V_THOFF = -4 mV typical). Once this threshold is reached, the embedded MOSFET only takes TD_OFF = 30 ns (typ.) to shutoff. Additionally, the drain source on resistance is R_DS(ON) = 15 mΩ (typ.)
• Smart synchronization feature
  
  • With the AR30N60PPA operating in CC mode, the smart SYNC pin synchronizes with the primary-side controller to avoid shoot-through from occurring. As a result, unfavorable reverse condition of the embedded MOSFET is prevented
• Multiple modes of operation
  
  • AR30N60PPA is ideally suited for the fast-charging capable AC/DC power converters implemented in either the flyback or the LLC-resonant topology, supporting many modes of operation such as DC, CC, and QR
• Fault detection and system protection
  
  • To protect the integrity of the system, the UVLO and OTP features of the AR30N60PPA guard against under voltage and over temperature, respectively
