The AOZ7203AV aims to replace the lossy diodes in the bridge rectifier circuit of an AC-DC power supply to cut the standby power and increase efficiency of high-end laptops and televisions, as well as power supplies for desktops, game consoles and servers.
The AOZ7203AV is an extension of the AOS active bridge driver AlphaZBL family and is available in an SOP-8L package. It has a high withstand voltage, a self-powered Vcc supply from the AC line, ultra-low operation current, and X-capacitor discharge (CB safety certified). Switching Power Supply Smps
A break-before-make circuit avoids the overlap of two gate driving while driving the low-side high voltage MOSFETs in an active bridge rectifier circuit.
With an input voltage of up to 600V, the AOZ7203AV has a wide operating (-40°C to +125°C) ambient temperature range and driving low RDSON HV MOSFETs to gain more efficiency improvement of AC power supply. These features make the AOZ7203AV an optimal solution for efficient replacement of
