This datasheet also covers the G5644-GlobalMixed variant, as both devices belong to the same 2.5a buck converter family and are provided as variant models within a single manufacturer datasheet.
General Description
The G5644 is a high efficiency, 2.5A buck converter with a high-side low RDS(ON) switch.
It operates from 4.75V to 20V input voltage range, and provides up to 2.5A continuous output current with the output voltage adjustable down to 0.8V.
Note: The manufacturer provides a single datasheet file (G5644-GlobalMixed-modeTechnology.pdf) that lists specifications for multiple related part numbers.
Note: Below is a high-fidelity text extraction (approx. 800 characters) for
G5644. For precise diagrams, and layout, please refer to the original PDF.
