LM27313XQMFX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM27313XQMFX/NOPB is a current-mode boost converter from Texas Instruments, housed in a compact SOT-23-5 package. It features an integrated 30V DMOS FET switch and operates at a fixed switching frequency of 1.6MHz. The device supports an input voltage range of 2.7V to 14V and provides an adjustable output voltage between 4V and 28V. It delivers up to 1.25A output current with a quiescent current of 2.1mA. Certified under AEC-Q100 Grade 1 standards, it functions reliably within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XQ' corresponds to the required automotive-grade AEC-Q100 qualification level. Confirm that the SOT-23-5 package variant matches your PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling instructions related to moisture sensitivity level classification during storage and reflow processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when board space is constrained but high output voltages are necessary. The 1.6MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.25A limit against peak load demands. Verify input voltage stability against the 2.7V minimum threshold. Evaluate thermal performance given the small package size under continuous load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM27313 series of DC-DC converters. It shares architectural similarities with other members like the LM27313XMFX but differs in packaging and qualification grades. The series focuses on providing efficient power conversion in ultra-small form factors suitable for modern portable electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM27313XMFX/NOPB or LM27313XMF/NOPB, though these may lack the specific automotive qualification or have different packaging options. Cross-reference pinouts and electrical characteristics carefully before substitution.
