AOZ5276QI-03 High-Current, High-Performance Smart Power Stage General Description The AOZ5276QI-03 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 AOZ5276QI-03 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. The AOZ5276QI-03 also includes an accurate module temperature monitor (TMON). TMON is a voltage sourced signal with a gain of 8mV/°C. The MOSFETs are individually optimized for operation in the synchronous buck configuration.
