Hello, I have a 5V power supply from which I want to produce -28V, @500uA max load current.
I've tried using lt1617-1 from linear technology but the simulation at LTspice shows an RMS current consumption of about 7-8mA, which is not acceptable for my application.
Any ideas on improving the circuit attached to lower overall current consumption (ideally around 1-2mA) or suggestions of any other implementations would be really helpful.
Thank you.
