Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
for low power apps you can use MAX1044/ICL7660 (Switched-Capacitor Voltage Converters) **broken link removed**
for more power you can use any switchin IC source like MC34063 in voltage inverting configuration (for this you need an inductor).
If you need more than 20mA (ICL7660 and HT7660) on the negative voltage, you can use also the MAX660A that can supply up to 100mA and converts from +5.5V to -5.5V.
