LM2585T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2585T-5.0/NOPB is a step-up switching regulator from Texas Instruments, part of the SIMPLE SWITCHER family. It operates with an input voltage range of 4 V to 40 V and provides a fixed 5 V output at up to 3 A. The device utilizes a TO-220-7 package for through-hole mounting. Key electrical parameters include a maximum switching frequency of 115 kHz, line regulation of 100 mV, and load regulation of 100 mV. It supports boost, flyback, and forward topologies with an efficiency of 93%. The operational temperature range spans from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• General-purpose power supply designs utilizing standard through-hole PCB layouts

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the required fixed output voltage variant. Confirm the package type corresponds to the intended board assembly process. Cross-reference the manufacturer datasheet for any recent pinout revisions or environmental certifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, high-current step-up solution is needed for industrial environments. The fixed 5 V output simplifies design compared to adjustable variants. Consider the TO-220-7 package for applications requiring direct heatsinking or high thermal dissipation capabilities. Verify that the input voltage source can handle the peak currents drawn during startup and full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2585 series of simple switchers designed for ease of use in power management applications. It serves as a cost-effective alternative to discrete solutions, integrating the controller, driver, and power switch on a single die. The series is widely recognized for its reliability in converting lower input voltages to higher stable outputs in demanding electronic systems.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2585T-ADJ/NOPB offers similar performance with an adjustable output voltage instead of a fixed 5 V setting. Other members of the LM2585 family may provide different fixed voltage options or packaging styles while maintaining the same core functionality and pinout compatibility.
