I'm designing a capacitor charge circuit using the LT3484-1. Its average current draw during charging is stated to be 225 mA however the instantaneous current can be as high as 550 mA. If I'm looking to power this from a USB port say, where the current limit is 500 mA, is there a circuit design modification that would lower the current draw? Or another part that uses less current? If it takes longer to charge that's not a problem, I'm just looking for a way to ease the load on my power supply.
