Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2590HVS-3.3

LM2590HVS-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVS-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down switching voltage regulator with a fixed 3.3V output. It supports an input voltage range of 4.5V to 60V and delivers up to 1A of output current. The device operates at a switching frequency of 150kHz and utilizes a TO-263 (D2PAK-7) surface-mount package. It features internal compensation for ease of design and includes thermal shutdown protection. The operational temperature range extends from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology simplifies design by requiring minimal external components
Fixed 3.3V output eliminates the need for external feedback resistors
Internal frequency compensation reduces component count and layout complexity

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in distributed power systems
Pre-regulation for downstream linear regulators
Efficient step-down conversion from higher bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number suffix matches your requirements, as the base model may have obsolete variants. Confirm RoHS compliance status via the manufacturer's official documentation, as non-compliant versions exist. Ensure the TO-263 package footprint aligns with your PCB design constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from inputs up to 60V. It is suitable for applications needing 1A continuous current with high efficiency. Consider the TO-263 package for adequate thermal dissipation without additional heatsinking in moderate load scenarios.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2590HV series, designed for high-voltage step-down applications. It differs from lower-voltage counterparts by supporting inputs up to 60V. The 'S' suffix indicates the surface-mount TO-263 package variant, while '/NOPB' denotes lead-free and halogen-free construction.
