LM2595T-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-12 is a SIMPLE SWITCHER power converter functioning as a 1A step-down voltage regulator. It operates at a fixed switching frequency of 150 kHz and provides a regulated 12V output. The device integrates a monolithic switching regulator to simplify design, requiring only four external components for basic operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a switching controller and power switch in a single package
Fixed 150 kHz switching frequency reduces passive component size
Includes internal thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Direct conversion from 48V bus
Pre-regulator for post-switching regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are held by Texas Instruments. Confirm the suffix indicates the standard TO-220 package. Ensure RoHS compliance status matches project requirements. Check for lead-free plating specifications on the terminals.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a fixed 12V output with up to 1A load current. It is suitable where input voltages range significantly higher than the output. Consider thermal management due to the linear drop across the internal switch. Verify input voltage does not exceed maximum ratings.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the SIMPLE SWITCHER family, designed for ease of use in DC-DC conversion. It replaces traditional linear regulators to improve efficiency. The T-12 variant specifically denotes the 12V fixed output configuration within the broader LM2595 series.
