LM2587T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2587T-12/NOPB is a step-up/flyback switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4 V to 40 V and provides a fixed output voltage of 12 V. The device supports a maximum output current of 5 A and features a typical switching frequency of 100 kHz. It utilizes a TO-220-5 through-hole package and functions within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-current power switch rated for 5 A continuous operation
• Fixed 12 V output option eliminates external feedback resistor networks
• Internal compensation simplifies design requirements for stable regulation

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Battery-powered equipment needing voltage boosting from lower source levels
• Distributed power supply architectures in telecommunications infrastructure

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' confirms the TO-220-5 through-hole package variant rather than the surface-mount 'S' version. Confirm the '-12' designation matches the required 12 V fixed output specification. Ensure the 'NOPB' suffix indicates lead-free and RoHS compliance status as per the manufacturer's latest documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust through-hole solution is preferred for thermal management or mechanical stability in industrial environments. The fixed 12 V output reduces bill-of-materials complexity compared to adjustable variants. Consider the 5 A current capability and 40 V maximum input rating to ensure adequate headroom for the target application's load and line conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2587 series of SIMPLE SWITCHER regulators, designed for ease of use with minimal external components. The series includes both adjustable and fixed voltage options across various packages. The TO-220 form factor distinguishes it from the smaller surface-mount counterparts while maintaining identical internal control logic and protection features.
