LM2586S-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2586S-ADJ/NOPB is a SIMPLE SWITCHER step-up/flyback regulator from Texas Instruments. It operates with an input voltage range of 4V to 40V and delivers up to 3A output current. The device features a fixed switching frequency of 100kHz, adjustable output voltage, and supports boost, flyback, and forward topologies. It is housed in a TO-263-7 surface-mount package and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates current-mode control for stable operation across wide input voltage ranges
• Supports multiple converter topologies including boost, flyback, and forward configurations
• Includes built-in thermal shutdown and cycle-by-cycle current limiting for protection

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power systems requiring step-up conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Texas Instruments before procurement. Confirm that the TO-263-7 package dimensions match your PCB footprint requirements. Ensure the application circuit design accounts for the 100kHz switching frequency and associated passive component selections to maintain stability and efficiency under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing non-isolated step-up or isolated flyback/forward converters requiring up to 3A. It is suitable for applications where a fixed 100kHz frequency allows for smaller magnetic components compared to lower-frequency alternatives. Consider the TO-263-7 package for its thermal performance in surface-mount layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2586 family of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion. Unlike the LM2596 buck regulator, the LM2586 focuses on step-up and isolated topologies. The 'S' suffix indicates the surface-mount TO-263 package, while 'ADJ' denotes adjustable output voltage capability.
