Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2585S-3.3/NOPB

LM2585S-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2585S-3.3/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 3.3V at up to 3A output current. The device utilizes a flyback topology with a typical switching frequency of 115kHz. It is housed in a surface-mount TO-263 package (DDPAK-5) and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated power switch capable of delivering high output current
Fixed internal feedback network for simplified design
Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered systems requiring voltage boost
General-purpose DC-DC conversion
Industrial control power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per Texas Instruments standards. Confirm the package type matches the required PCB footprint. Ensure the fixed 3.3V output variant aligns with system requirements, as other voltage options exist within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a wide input voltage range up to 40V. Consider the 3A current capability and TO-263 thermal performance for heat dissipation needs. Compare against adjustable variants if flexible output voltages are necessary instead of the fixed configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2585 series of SIMPLE SWITCHER regulators, designed for efficient step-up applications. It shares architectural similarities with other members of the family but is distinguished by its fixed 3.3V output setting and specific pinout configuration within the TO-263 package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2585 variants with different fixed output voltages or adjustable versions like the LM2585S-ADJ/NOPB, provided the circuitry is modified accordingly.
