LM2585S-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2585S-5.0/NOPB is a step-up switching voltage regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4V to 40V and provides a fixed output voltage of 5.0V at up to 3A output current. The device utilizes a flyback topology with a typical switching frequency of 115kHz. It is housed in a TO-263 surface-mount package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer datasheet to confirm lead-free compliance and exact electrical tolerances. Ensure the selected package variant matches the required PCB footprint and thermal management strategy for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a wide input range. Consider the TO-263 package for its thermal dissipation capabilities relative to smaller SMD options. Evaluate the 115kHz switching frequency against EMI constraints and inductor size requirements compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2585 series of SIMPLE SWITCHER regulators, designed for high-efficiency step-up applications. The 'S' designation indicates the TO-263 surface-mount package, while the '-5.0' specifies the fixed 5-volt output configuration within the broader adjustable or fixed-voltage product line.
