The MAX860IUA+ from Maxim Integrated is a high-efficiency, CMOS charge-pump voltage converter that is adept at increasing or inverting DC voltages. It is a versatile component that is particularly suitable for applications requiring small, low-power devices to generate a higher voltage from a lower voltage supply or to provide a negative voltage rail.

Key Features

• Voltage Conversion: The device can double input voltages ranging from +2.5V to +5.5V or split a single supply into a ± output.
• High Power Efficiency: With a 99% power efficiency for most of the load conditions, the MAX860IUA+ ensures minimal power loss during voltage conversion.
• Low Noise Operation: It incorporates a 45kHz (typical) oscillator that reduces output ripple and minimizes noise, making it ideal for sensitive applications.
• Compact Design: The device comes in a small 8-pin µMAX package, which is perfect for space-constrained applications.
• Versatility: It can be used in a variety of configurations, including voltage doublers, inverters, or voltage multipliers, providing design flexibility.
