For some simple led curcuits I would like to use just a single AA cell. Are there any simple low part count _discrete_ solutions for a converter that has an efficiency of >50% with a standby current or no load current of less than 1mA? Charge pump is preferred, but if it needs a single coil it's also ok. Thanks in advance.
