Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2651MTCX-ADJ

LM2651MTCX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2651MTCX-ADJ is a synchronous step-down DC/DC converter from Texas Instruments, housed in a 16-pin TSSOP package. It supports an input voltage range of 4 V to 14 V and delivers up to 1.5 A output current. The adjustable output voltage spans from 1.238 V to 13 V. Operating at a switching frequency of approximately 300 kHz, the device functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates high-side and low-side N-channel power MOSFETs for synchronous rectification
Features internal compensation to minimize external component count
Includes programmable soft-start and cycle-by-cycle current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient step-down conversion
Industrial control modules with single-supply requirements

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'X' denotes tape-and-reel packaging rather than tube configuration. Confirm RoHS compliance status via the manufacturer datasheet, as lead-free variants typically carry the NOPB suffix. Ensure the ordering part number matches the required package style for your assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for moderate current loads under 1.5 A. The fixed 300 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the input voltage remains within the 4 V to 14 V window to ensure stable operation and proper regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM265x family of synchronous buck converters designed for high efficiency and small footprint. It shares architectural similarities with the LM2655 but offers lower output current capability. The family targets applications where board space is constrained and thermal management must be optimized through integrated power stages.
