XC9141A55CMR-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9141A55CMR-G is a synchronous step-up DC/DC converter manufactured by Torex Semiconductor Ltd. It operates within an input voltage range of 0.65 V to 6 V and provides a fixed output voltage of 5.5 V. The device supports an output current of up to 500 mA and utilizes a switching frequency of 1.2 MHz. Designed for surface mount installation, it is housed in a compact SOT-753 (SC-74A) package with five pins. The component functions reliably across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'A55' confirms the 5.5 V fixed output setting. Confirm the 'CMR-G' designation matches the required SOT-753 package and RoHS compliance status. Ensure compatibility with the intended input voltage range of 0.65 V to 6 V before integration into the design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.5 V output is required from a low-voltage source. The 1.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 500 mA output current capability meets the load requirements of the target application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series of synchronous step-up converters from Torex Semiconductor. The series is characterized by low input voltage operation and high efficiency. The XC9141A55CMR-G specifically denotes the variant with a 5.5 V fixed output, distinguishing it from other models in the family with different voltage settings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141B50CMR-G: Offers similar topology but provides a 5 V output instead of 5.5 V. XC9141A30CMR-G: Provides a 3.0 V fixed output. Verify output voltage compatibility before substitution.
