G5390-50RC1U
Ultra Low Quiescent Current, Hysteretic DC-DC Boost Converter
The G5390 is an ultra low quiescent current, hysteretic DC-DC boost converter. The device can operate from a 0.7V to 5.0V supply and the output voltage is fixed from 2.2V to 5.0V. The output is not connected to the input in shutdown mode and the shutdown current is less than 100nA. The G5390 features auto-bypass mode when the device directly connect the input to the output voltage if the VIN exceeds VOUT. In light load operation, the G5390 enters sleep mode. Most of the operating blocks are turned off for saving power. The G5390 also offers adjustable low battery detection. The LBO output is pulled to logic low if the battery voltage decreases below the threshold defined by external resistors on pin LBI. Alternately, the LBO output is working as Power-Good function when LBI is connected to GND.
