LM2586T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2586T-12/NOPB is a SIMPLE SWITCHER step-up/flyback regulator from Texas Instruments. It operates with an input voltage range of 4V to 40V and provides a fixed 12V output at up to 3A switch current. The device features a 100kHz switching frequency, current-mode control, and operates within a junction temperature range of -40°C to 125°C. It is housed in a TO-220-7 through-hole package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Supports step-up, flyback, and forward converter topologies
• Integrates internal power switch for simplified design
• Includes thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial power supplies
• Battery-powered systems requiring voltage boost
• General-purpose DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free status and RoHS compliance as per manufacturer documentation. Confirm the 'T' suffix indicates the TO-220-7 through-hole package variant rather than surface-mount options. Ensure the fixed 12V output version matches the application requirement instead of the adjustable variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from a wide input range up to 40V. The TO-220-7 package suits applications needing robust thermal performance via through-hole mounting. Consider the 3A switch current limit and 100kHz frequency for inductor sizing and efficiency requirements compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2586 family of SIMPLE SWITCHER regulators. It shares core architecture with other variants like the LM2586S series but differs in package type and mounting style. The family is designed for efficient step-up and flyback applications with integrated protection features.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2586T-12/NOPB is the direct equivalent. LM2586T-ADJ/NOPB offers adjustable output. LM2586S-12/NOPB provides the same electrical specifications in a surface-mount TO-263-7 package.
