General Description

The AOZ5273QI is a general-purpose Smart Power Stage (SPS) consisting of two asymmetrical MOSFETs and an integrated driver for high current, high frequency DC-DC converters.

The AOZ5273QI provides an output voltage signal (IMON), which represents the real-time module current with a gain of 5mV/A.

The IMON signal can be directly used to replace inductor DCR sensing or resistor sensing in multiphase voltage regulator systems without the need for temperature compensation.
