DC/DC Adjustable Charge Pump Voltage Converter 1.5V-10V In SOIC-8

The Texas Instruments Adjustable Charge Pump Voltage Converter is a switched capacitor device designed to convert a positive voltage in the range of +1.5V to +10V to the corresponding negative voltage of -1.5V to -10V. Functioning as a pin-for-pin replacement for the industry-standard 7660, this converter offers seamless integration into existing designs while delivering reliable performance.

Operating over the full temperature and voltage range without the need for an external diode, it simplifies circuit design and reduces component count. The device uses a built-in oscillator to switch four power MOS switches and charge two inexpensive electrolytic capacitors, ensuring high efficiency and straightforward application.
