MAX1044 1.5–5.5V Charge Pump Voltage Converter IC | DC-DC Inverter/Doubler, Low Power, DIP/SOP Package | Xinbole

The MAX1044 is a high-efficiency CMOS charge pump DC-DC voltage converter IC designed for voltage inversion, voltage doubling, and split supply generation without the need for inductors. It uses advanced switched-capacitor charge pump technology to deliver stable, low-noise voltage conversion with high efficiency, reduced component count, and simplified circuit design.

Operating over a wide input range of 1.5V to 5.5V, the MAX1044 provides excellent flexibility for low-voltage and battery-powered systems. Its internal high-speed switching architecture ensures efficient energy transfer, low power loss, and improved thermal performance compared to traditional regulator-based or discrete converter solutions. This results in compact designs with higher reliability and reduced heat generation.

The device offers stable output voltage conversion with low ripple characteristics, making it suitable for sensitive analog and digital circuits. It is available in both DIP and SOP package types, supporting easy prototyping, PCB integration, and high-density production designs.
