Voltage Regulators - DC DC Switching Regulators Overview

The LM2598T-5.0/NOPB is a SIMPLE SWITCHER power converter featuring an integrated 1-A step-down switching regulator. It operates from an input voltage range of 4.5 V to 40 V and provides a fixed 5-V output. The device utilizes a 150-kHz switching frequency, allowing for the use of small inductors and capacitors. It includes internal frequency compensation and a 52-mA driver capable of handling up to 3-A peak current. The regulator incorporates thermal shutdown and current limit protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switching regulator with fixed 150-kHz oscillator
Internal frequency compensation eliminates external compensation components
Built-in thermal shutdown and current limit protection circuits
Requires minimal external passive components for operation

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for switching regulators
Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free status and RoHS compliance. Confirm the package type matches the TO-220-7 through-hole requirement. Ensure the fixed 5.0-V output variant aligns with circuit design needs, as adjustable versions exist within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5-V output at 1 A is required from a high-voltage bus. The TO-220-7 package offers robust thermal performance for through-hole mounting. Consider the 150-kHz frequency trade-off between component size and efficiency compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Texas Instruments SIMPLE SWITCHER family, designed for simplified power supply designs. It serves as a cost-effective solution for medium-current applications where board space is limited but thermal dissipation capabilities are needed via the through-hole package.
