Download the G5380B datasheet PDF.
This datasheet also covers the G5380B-GlobalMixed variant, as both devices belong to the same high efficiency 8a synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.
General Description
G5380B is a 8A, synchronous DC/DC buck converter with integrated 20mΩ N-channel high-side MOSFET and 17mΩ N-channel low-side MOSFET.
Key Features
Ultra-High Efficiency.
Low Quiescent Current of 40µA.
Integrated 17mΩ at VCC=5V N-Channel MOSFET for Low Side.
Integrated 20mΩ at VCC=5V N-Channel MOSFET for High Side.
Note: The manufacturer provides a single datasheet file (G5380B-GlobalMixed-modeTechnology.pdf) that lists specifications for multiple related part numbers.
