Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2591HVS-3.3

LM2591HVS-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVS-3.3 is a step-down switching regulator IC manufactured by UMW, part of the SIMPLE SWITCHER family. It operates with an input voltage range up to 60V and provides a fixed 3.3V output at a maximum current of 1A. The device features a 150kHz internal oscillator and utilizes a TO-263-5 (D2PAK) surface-mount package. Designed for high efficiency, it includes thermal shutdown and current limit protection, operating within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated 150kHz fixed-frequency oscillator simplifies external component selection
Built-in thermal shutdown and current limiting ensures operational reliability under fault conditions
High input voltage capability supports direct conversion from common bus voltages

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in industrial control systems
Input voltage step-down for embedded microprocessor power supplies
Battery-powered equipment requiring efficient voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer marking on the component body to confirm UMW origin, as this series is also produced by Texas Instruments. Ensure the suffix matches the fixed 3.3V output variant. Check RoHS compliance status against specific batch documentation if required for regulatory adherence.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.3V output is required rather than an adjustable version. Confirm that the load current does not exceed 1A continuous. Verify that the input voltage remains within the 60V maximum rating. Consider the thermal performance of the TO-263 package for the intended ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2591HV series of high-voltage step-down regulators. It shares functional similarities with the LM2590HV and LM2592HV series, differing primarily in output current ratings and specific pin configurations. The 'HVS' designation indicates a high-voltage capable surface-mount variant designed for robust power management applications.
