Sipex Launches the SP6661 Charge Pump Inverter/Doubler

Sipex Corp. (Billerica, MA) announced the availability of its new SP6661 high-speed, high-current charge pump inverter/doubler. The SP6661 can be configured as either a voltage doubler, with Vin from 2.5V to 5.0V for a Vout of 5V to 10V, or a voltage inverter, with Vin from 1.5V to 5.0V for a Vout of -1.5V to –5.0V.

The SP6661 operates at 900kHz, using 1uF ceramic capacitors. Sipex claims that the device delivers up to 200mA, with efficiencies of 85 percent or higher. The SP6661 is targeted at board-level applications where some electronics require non-standard board level supply voltages such as read amplifiers in disk drives. It is packaged in an eight-lead MSOP and an eight-lead nSOIC and operates over the temperature range -40 to 85 degrees C.

“The SP6661 makes obsolete the slower, lower current charge pumps available today," said Todd Sherman, manager of Sipex's power management product line. “Not only is the SP6661 faster, smaller and more powerful than its closest competitor, it uses smaller, less expensive, more readily available 1µF ceramic capacitors."

The SP6661 is currently available for $0.86 each in 10,000-piece quantities.
