LM2594HVN-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVN-ADJ/NOPB is a SIMPLE SWITCHER® high-voltage step-down DC/DC converter from Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and provides an adjustable output voltage between 1.2 V and 57 V. The device delivers a maximum output current of 500 mA at a fixed switching frequency of 150 kHz. Packaged in an 8-pin PDIP through-hole format, it functions as a buck regulator suitable for industrial and automotive applications requiring wide input voltage tolerance.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package type matches the design requirements, as this specific part number denotes the PDIP-8 through-hole variant. Confirm that the application circuit supports the required thermal dissipation for the chosen operating conditions. Ensure the input voltage does not exceed the 60 V absolute maximum rating during transient events.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole solution is preferred over surface-mount options within the LM2594HV family. It is appropriate for designs requiring an adjustable output voltage rather than fixed voltage variants. Consider the thermal performance of the PDIP-8 package relative to the expected load current and ambient temperature constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2594HV series, which extends the standard LM2594 capabilities to handle higher input voltages. The HV designation indicates enhanced breakdown voltage ratings for the internal power switch. The ADJ suffix specifies the adjustable output configuration, allowing flexibility in setting the regulated voltage level via external resistors.
