Hi,
We would like to design an USB host device, but would like the device to be able to power USB peripherals (up to 500mA current) from battery when not connected to DC power. For this purpose, it seems that a power IC which could buck-up 3.7V battery voltage to 5V is needed.
Could someone recommend such a power IC for this purpose?
Additionally, is any such power IC also have built-in current-limiting ability so that we no longer need extra current-limiting switches?
