Description
The ADM660/ADM8660 is a charge-pump voltage converter that can be used to either invert the input supply voltage giving VOUT = –VIN or double it (ADM660 only) giving VOUT = 2 X VIN. Only two small external capacitors are needed for the charge pump. Output currents up to 50 mA with greater than 90% efficiency are achievable, while 100 mA achieves greater than 80% efficiency. Input voltages ranging from +1.5 V to +7 V can be inverted into a negative –1.5 V to –7 V output supply, which is suitable for generating a negative rail in single power supply systems.
