AOZ7203AV Zero Bridge Loss AlphaZBLTM Controller General Description The AOZ7203AV is a Zero Bridge Loss AlphaZBLTM Controller that controls the two external N-channel MOSFETs to replace two low-side diodes when used in AC/DC diode-bridge application. The AOZ7203AV can help the power supply to reduce power consumption and heat dissipation, and can make it easier to reach the titanium level efficiency and shorten engineering development time. In diode-bridge application, the AOZ7203AV senses the AC input voltage and reduces the forward conduction loss to the minimum value. The AOZ7203AV is self-powered from the AC line without the need of an extra voltage supply. The AOZ7203AV is available in a SO8 package.
