Hi,
I need a 5V/500mA boost regulator that can give me 5V from a 3.7V Li-Ion battery. Currently I am using the L6920 together with a 18uH inductor. The problem with the current solution is noise and ripple. I can hear a high frequently squealing from the inductor when the regulator is loaded. In addition there is +/-60mV ripple on the 5V output. I want a small ripple and I don't want to hear the conductor squealing.
Any suggestions for a 5V/500mA boost regulator that I can use instead?
