General Description
The G5175 device features three synchronous 5.5V input range high efficiency buck converters. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.
Ordering Information
The converters can operate in 5V systems and have integrated power
transistors. The output voltage can be set externally using a resistor divider to any value between 1.0V and close to the input su...
