The SP6661 is a CMOS monolithic voltage DC-DC converter that can be implemented as a high voltage inverter or positive voltage multiplier. A -1.5V to -5.0V output at +1.5 V to +5.0 V input due to high voltage inverter. As a +5.0 V to 10.0 V output voltage multiplier, it can be input from +2.5 V to +5.0 V. The SP6661 is ideal for battery powered and circuit board voltage conversion applications with a typical operating current of 3mA and high efficiency levels (>90%) within its load current range. Typical end products for this device are disk drives holding supplies, operational amplifiers and power connectors, medical devices, and hand and notebook computers. SP6661 is available in 8-pin NSOIC and μSOIC packages.
