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.
The AOZ5273QI 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. The High-Side (HS)
MOSFET is optimized to achieve low capacitance and
gate charge for fast switching with low duty cycle
operation. The Low-Side (LS) MOSFET has ultra-low ON
resistance to minimize conduction loss. The standard
5mm x 6mm QFN package is optimally designed to
minimize parasitic inductance for minimal EMI signature.
