AOZ5273QI 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...
