LM2598T-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2598T-ADJ/NOPB is a SIMPLE SWITCHER step-down switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage from 1.23 V to 37 V. The device supports a maximum output current of 1 A at a fixed switching frequency of 150 kHz. It utilizes a TO-220-7 through-hole package and functions within an operating temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic power switch rated for 1 A continuous load current
• Fixed 150 kHz internal oscillator for simplified external component selection
• Built-in thermal shutdown circuitry to protect against overheating
• Adjustable output voltage capability via external resistor divider

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation modules
• Pre-regulators for switching regulators
• Efficient standard 5-V logic supply step-down converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220-7 through-hole package variant distinct from surface-mount versions. Confirm the 'ADJ' designation ensures adjustable output functionality rather than fixed voltage options. Ensure compliance with RoHS standards as indicated by the NOPB suffix before final procurement integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust through-hole solution is required for high-current step-down applications up to 1 A. The fixed 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the TO-220 package for heat dissipation requirements in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2598 series of SIMPLE SWITCHER regulators, designed for efficient DC-DC conversion. It serves as a through-hole alternative to surface-mount variants like the LM2598S series, offering similar electrical characteristics but with different mounting and thermal management profiles suitable for prototyping or industrial enclosures.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2598T-ADJ/NOPB is functionally equivalent to LM2598T-ADJ. Surface-mount equivalents include LM2596SX-ADJ/NOPB for higher current or LM2598S-ADJ/NOPB for identical current ratings.
