LM2653MTCX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2653MTCX-ADJ is a synchronous step-down switching regulator from Texas Instruments, housed in a 16-pin TSSOP package. It operates with an input voltage range of 4 V to 14 V and provides an adjustable output voltage between 1.5 V and 5 V. The device delivers a maximum output current of 1.5 A at a fixed switching frequency of 330 kHz. It functions within a junction temperature range of -40°C to +125°C and includes integrated features such as cycle-by-cycle current limiting and thermal shutdown protection.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MTCX' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the 'ADJ' designation matches the requirement for an adjustable output voltage configuration rather than a fixed voltage variant. Ensure the NOPB lead-free status aligns with environmental compliance standards for the target manufacturing region.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for moderate current loads up to 1.5 A. The fixed 330 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance in the TSSOP-16 package relative to the expected ambient temperature and load conditions to ensure reliable operation within the specified temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM265x family of high-efficiency synchronous buck converters designed for space-constrained applications. The family shares common control architectures but varies in output current capabilities and package options. The LM2653 specifically targets applications requiring a balance between size, cost, and performance for single-output DC-DC conversion tasks.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM2653 variants with different packaging options such as tube or exposed pad configurations if thermal management requirements differ. Verify compatibility with alternative suppliers offering equivalent synchronous buck controllers with similar input voltage ranges and current ratings.
