LM2593HVS-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2593HVS-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications up to 60 V. It delivers a fixed 5 V output with a maximum current of 2 A. Operating at a fixed switching frequency of 150 kHz, the device utilizes a buck topology and is housed in a TO-263-8 (D2PAK) surface-mount package. The unit supports an input voltage range of 4.5 V to 60 V and functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch capable of handling high input voltages up to 60 V
• Fixed internal switching frequency simplifies external component selection
• Built-in thermal shutdown and current limiting for operational protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial control systems
• High-voltage bus distribution networks
• Embedded system power supplies requiring isolated or non-isolated step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required package variant and temperature rating. Cross-reference the RoHS status and REACH compliance details directly with the official documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs exceeding standard logic levels. The 2 A capacity suits moderate load applications without external pass transistors. Consider the 150 kHz frequency for balancing efficiency and passive component size. Verify that the TO-263 package thermal performance meets the system's heat dissipation requirements under maximum load conditions.

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 LM2592HV but offers increased output current capability. The series is characterized by its ability to operate directly from high-voltage buses, reducing the need for pre-regulation stages in power distribution designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2593HVS-ADJ serves as an adjustable alternative within the same family. For lower current requirements, the LM2592HVS series may be considered if the 1 A limit suffices. Direct pin-to-pin replacements should be verified against the latest TI datasheets for any functional updates.
