Eight MOSFETs have three package options
Eight products have been added to the 60V MOSFET family. They are designed for synchronous rectification in flyback converters, used in quick chargers for portable devices, such as smart phones. AO4262E, AO4264E, AO4268, AON6262E, AON6264E, AON6268, AON7262E, and AON7264E offer 6.5, 8.5 and 13.5mΩ on-resistance at 4.5V gate drive voltage. They are available in three package types:  SO-8, DFN5x6, and DFN3x3.

Higher power charger circuits to charge devices in less time is driving demands for MOSFETs for synchronous rectification. The latest additions to the family directly increase the output current of the charger circuit, using a simple circuit design keeping high current conversion inside the charger. A 60V platform is selected for better on-resistance and voltage tolerance balance. All are optimized for low on-resistance at a lower gate drive voltage, which is normally around 4.5V. Switching losses depend on the control scheme used in the charger circuit. The company’s AlphaSGT process is claimed to provide best-in-class on-resistance with very low parasitic capacitance, for lower switching loss. The devices are also tuned to keep EMI suppression simple and reliable.
