FAN5601MP18X is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Fairchild Semiconductor. Its product description is IC REG CHRG PUMP 1.8V 250MA 6MLP. Review the specifications below when checking this part for your BOM.
The FAN5601MP18X is a regulated step-down charge pump DC/DC converter manufactured by Fairchild Semiconductor. It provides a fixed positive output voltage of 1.8V with an input voltage range from 2.7V to 5.5V. The device operates in a surface-mount 6-MLP package and supports an operating temperature range of -40°C to 85°C.
Verify the manufacturer origin, as the component is associated with both Fairchild Semiconductor and ON Semiconductor due to corporate acquisition history. Confirm the specific package type matches the design requirements. Ensure compliance with RoHS standards if required by the target market regulations.
Select this component when a fixed 1.8V output is required from a 2.7V to 5.5V input source within a small footprint. Consider the charge pump topology for applications where linear regulators are inefficient or where specific step-down conversion is needed without inductors.
This part belongs to the FAN5601 series of switched capacitor regulators. It is functionally similar to other parts in the family but distinguished by its fixed 1.8V output designation. The MP18X suffix indicates the specific voltage variant and packaging configuration.
Check for direct substitutes within the FAN5601 series or compatible charge pump regulators from ON Semiconductor. Verify pin compatibility and electrical specifications before substitution.
