GENERAL 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 (ADM660ARZ-REEL7 only) giving VOUT = 2  VIN. Input voltages ranging from +1.5 V to +7 V can be inverted into a negative –1.5 V to –7 V output supply. This inverting scheme is ideal for generating a negative rail in single power supply systems. 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.

A Frequency Control (FC) input pin is used to select either 25 kHz or 120 kHz charge-pump operation. This is used to optimize capacitor size and quiescent current. With 25 kHz selected, a 10 µF external capacitor is suitable, while with 120 kHz the capacitor may be reduced to 2.2 µF. The oscillator frequency on the ADM660ARZ-REEL7 can also be controlled with an external capacitor connected to the OSC input or by driving this input with an external clock. In applications where a higher supply voltage is desired it is possible to use the ADM660ARZ-REEL7 to double the input voltage. With input voltages from 2.5 V to 7 V, output voltages from 5 V to 14 V are achievable with up to 100 mA output current. The ADM8660 features a low power shutdown (SD) pin instead of the external oscillator (OSC) pin. This can be used to disable the device and reduce the quiescent current to 300 nA.

The ADM660ARZ-REEL7 is a pin compatible upgrade for the MAX660, MAX665, ICL7660, and LTC1046.

The ADM660/ADM8660 is available in 8-lead DIP and narrow-body SOIC. The ADM660ARZ-REEL7 is also available in a 16-lead TSSOP package.
