Voltage Regulators - DC DC Switching Regulators datasheet and documents for MAX1044C/D

MAX1044C/D

Voltage Regulators - DC DC Switching Regulators Overview

The MAX1044C/D is a monolithic CMOS switched-capacitor voltage converter manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.5V to 10.0V and delivers an output current of 10mA with a typical 0.5V output drop. The device features a BOOST pin that increases the switching frequency above the audio band, reducing external capacitor size requirements. It offers 98% typical power-conversion efficiency and requires no external diode for higher-voltage operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Monolithic CMOS switched-capacitor architecture
Integrated BOOST pin for high-frequency operation
Pin-compatible with industry-standard ICL7660

Voltage Regulators - DC DC Switching Regulators Applications

-5V supply generation from +5V logic supplies
Op-amp power supplies
EIA/TIA-232E and EIA/TIA-562 power supplies
Portable telephones and personal communications equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package type and temperature grade match design specifications. Check for RoHS compliance status if required by assembly standards. Review datasheet revisions for any functional updates or pinout changes before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-noise voltage inversion or multiplication solution is needed. The integrated BOOST pin allows for smaller external capacitors compared to standard converters. Ensure input voltage remains within the 1.5V to 10.0V range. Consider thermal performance and load current requirements against the 10mA delivery capability.

Voltage Regulators - DC DC Switching Regulators Part Context

The MAX1044 belongs to the family of switched-capacitor voltage converters designed for portable applications. It serves as a direct replacement for the ICL7660 while offering improved performance through the BOOST feature. This series supports various voltage conversion topologies including inversion, doubling, and division within a single miniature package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The MAX1044 is pin-compatible with the ICL7660 and LTC1044. Verify that substitute devices support the same operating voltage range and output current capabilities. Ensure the alternative includes the BOOST pin functionality if reduced capacitor size is a design requirement.
