The BD8316GWL converter is a power supply solution designed for portable devices. It can operate with a wide input voltage range of 2.5V~5.5V and has a 1μA standby current. It is possible to enable and disable each channel. Users can select which channel to output to, by changing the STB1 and STB2 pins to High or Low. The small package design is suitable for miniaturizing the power supply.
