LM2593HVS-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2593HVS-5.0/NOPB is a SIMPLE SWITCHER step-down switching regulator manufactured by Texas Instruments. It operates at a fixed switching frequency of 150 kHz and delivers a maximum output current of 2 A with a fixed 5 V output voltage. The device supports an input voltage range from 4.5 V to 60 V. It is housed in a TO-263-8 (D2PAK) surface-mount package and functions as a non-synchronous buck converter. The component is rated for operation within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch enables direct connection to high-input voltage buses without external components.
• Fixed internal switching frequency simplifies external component selection and reduces filter size requirements.
• Built-in thermal shutdown and current limit protection ensure reliable operation under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial control systems
• High-voltage bus conversion in telecommunications equipment
• Battery-powered systems requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the latest manufacturer datasheet. Confirm the TO-263-8 pinout matches the target PCB footprint design. Ensure the fixed 5.0 V output variant aligns with system voltage requirements, 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 is required from inputs up to 60 V. The 2 A current rating suits moderate load applications. Consider the 150 kHz frequency for balancing efficiency and passive component size. Verify that the non-synchronous topology meets efficiency targets compared to synchronous alternatives if higher performance is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2593HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2590 and LM2596 families but offers a higher 2 A output capability compared to the 1 A LM2590. It is designed for high-efficiency, easy-to-use DC/DC conversion solutions in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2593HVS-ADJ/NOPB provides an adjustable output version within the same package and electrical family. LM2590HVS-5.0/NOPB is a lower-current (1 A) alternative in the same series. Cross-reference pinouts and thermal characteristics before substitution.
