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

LM2590HVS-3.3/NOPB

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 voltage regulator with a fixed 3.3 V output. It operates at a switching frequency of 150 kHz and supports an input voltage range from 4.5 V to 60 V. The device delivers a maximum output current of 1 A through a single channel. It utilizes a TO-263 package for surface mount installation and is rated for operation between -40 °C and +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage switch capable of handling up to 60 V input
Fixed 3.3 V output configuration eliminates external feedback resistors
Internal frequency compensation simplifies external component requirements

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in industrial equipment
Power supplies for embedded systems requiring stable 3.3 V rails
Battery-powered applications utilizing high-input voltage sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'S' indicates the surface-mount TO-263 variant distinct from other packages. Confirm RoHS compliance status via the manufacturer datasheet, as legacy versions may differ. Ensure the ordering part number matches the exact thermal pad and pinout requirements for your PCB layout design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required without external resistor networks. It is suitable for designs needing high input voltage tolerance up to 60 V. Consider the 1 A current limit and 150 kHz frequency for inductor sizing and thermal management calculations relative to the TO-263 package capabilities.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series, designed for high-voltage step-down conversion. It shares architectural similarities with the LM2596 but offers higher input voltage capability. The 'NOPB' suffix denotes lead-free and RoHS-compliant manufacturing, distinguishing it from older non-compliant variants within the same product family.
