LM2591HVS-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVS-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, featuring a fixed 3.3 V output and 1 A maximum output current. It utilizes a buck topology with a standard switching frequency of 150 kHz. The device supports an input voltage range of 4.5 V to 60 V and operates within a temperature range of -40 °C to +125 °C. Packaged in a TO-263-5 surface-mount case, it includes internal frequency compensation and a shutdown feature.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage switch rated for up to 60 V input
Fixed 3.3 V output option eliminates external feedback resistors
Built-in thermal shutdown and current limit protection
Requires minimal external components for implementation

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital logic circuits
Pre-regulation for downstream linear regulators
Battery-powered systems requiring step-down conversion
Industrial control system power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status. Ensure the package designation matches the required TO-263-5 footprint. Confirm the '-3.3' variant aligns with the specific target voltage requirement rather than selecting an adjustable version.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required alongside a wide input voltage range up to 60 V. The 1 A current rating suits moderate load applications. Consider the TO-263-5 package for thermal management needs compared to smaller SMD options.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2591HV series, designed for high-voltage step-down applications. It complements other variants like the adjustable LM2591HVSX-ADJ/NOPB and higher-current counterparts such as the LM2592HV series. The family focuses on simplified design through integrated compensation.
