The ICL7660CSA+ is a switched-capacitor Voltage Converter. The monolithic, CMOS switched-capacitor voltage converter that invert, double, divide or multiply a positive input voltage. They are pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with no external diode over the full temperature range. They deliver 10mA with a 0.5V output drop. The ICL7660 combine low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip.
• 98% Typical power-conversion efficiency
• No-load supply current of 200µA maximum at 5V
• No external diode required for higher-voltage operation
