LM2596TV-12

Voltage Regulators - DC DC Switching Regulators Overview

The TAEJIN LM2596TV-12 is a step-down switching regulator module based on the LM2596 architecture, designed for efficient voltage conversion. It integrates a 3A current switch and operates from an input voltage range up to 40V DC. The device provides a fixed 12V output with high efficiency, typically exceeding 70%. It includes internal frequency compensation and a 52kHz oscillator for stable operation without external timing components. The module features thermal shutdown and current limiting protection mechanisms to ensure reliability under overload or short-circuit conditions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer marking against TAEJIN documentation to confirm authenticity. Ensure the package type matches the required PCB footprint. Check for any suffix variations that might indicate different temperature grades or packaging formats. Confirm compliance with relevant safety standards if used in certified end-products.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from a higher DC bus voltage. Consider the maximum input voltage limit of 40V and the continuous current capability of 3A. Evaluate thermal management requirements due to power dissipation at high input-output differentials. Verify compatibility with the desired switching frequency and inductor selection guidelines provided in the datasheet.
