Additional Details:

The AO4452L has a drain-source voltage (VDS) rating of -30V and a continuous drain current (ID) of -7.5A. It is available in a SO-8 package. The static drain-source on-resistance (RDS(on)) is typically 22 mΩ at VGS = -10V and 32 mΩ at VGS = -4.5V. These low RDS(on) values contribute significantly to the device's efficiency. It's designed to operate over a temperature range of -55°C to +150°C.
