LM2586S-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2586S-3.3/NOPB is a SIMPLE SWITCHER step-up, flyback, or buck-boost regulator from Texas Instruments. It operates with an input voltage range of 4V to 40V and provides a fixed 3.3V output. The device supports up to 3A switch current with a switching frequency of 100kHz to 200kHz. It utilizes current-mode control for fast transient response and includes internal compensation. The component is housed in a TO-263 (DDPAK-7) package and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch capable of delivering high output currents
• Current-mode control architecture ensures rapid transient response
• Internal frequency compensation simplifies external circuit design
• Fixed 3.3V output option eliminates external resistor networks

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring step-up or inverted regulation
• Battery-powered applications needing extended runtime via boost topology
• On-card regulation for systems with wide input voltage variations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package marking matches the TO-263 form factor. Ensure the ordering part number aligns with the fixed 3.3V output variant rather than adjustable versions. Cross-reference datasheet revisions for any pinout or thermal pad modifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from inputs between 4V and 40V. It is suitable for designs needing up to 3A load current in step-up, flyback, or buck-boost configurations. Consider the TO-263 package for thermal management requirements. Evaluate the 100kHz to 200kHz switching frequency against inductor size constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2586 family of SIMPLE SWITCHER regulators. It shares architectural similarities with other variants like the LM2586S-ADJ but offers a fixed output voltage. The series is designed for non-isolated DC/DC conversion, providing a cost-effective solution for medium-power applications compared to linear regulators.
