LM2594HVN-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVN-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications. It operates with an input voltage range of 4.5 V to 60 V and provides a fixed 12 V output at up to 500 mA. The device utilizes a buck topology with a switching frequency of 150 kHz. It features a shutdown function and low static current of 5 mA. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage switch capable of handling inputs up to 60 V
• Fixed 12 V output configuration for simplified design
• Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Distributed power supply architectures
• Battery-powered systems with high input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HV' indicates high-voltage input capability (up to 60 V) compared to standard variants. Confirm the 'N' suffix denotes lead-free/RoHS compliance. Ensure the 'V' suffix matches the required PDIP-8 through-hole package rather than surface-mount SOIC options. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12 V output is required from a high-voltage source up to 60 V. The PDIP-8 package is suitable for prototyping or applications requiring through-hole assembly. Consider the 150 kHz switching frequency for inductor size trade-offs. Verify that the 500 mA output current meets the load requirements without exceeding thermal limits in the chosen enclosure.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2594HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2594MX-12/NOPB but differs in package type (PDIP vs. SOIC) and maximum input voltage rating. The series is known for reducing external component count while maintaining robust performance in step-down converter topologies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2594HVM-12/NOPB offers identical electrical specifications but uses an 8-SOIC surface-mount package instead of PDIP-8.
