LM2594HVM-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVM-ADJ/NOPB is a SIMPLE SWITCHER step-down voltage regulator 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 37 V. The device supports a maximum output current of 500 mA with a fixed switching frequency of 150 kHz. It utilizes a buck topology and is housed in an 8-pin SOIC surface-mount package. The component functions within a 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 sources without external components.
• Fixed 150 kHz internal oscillator allows for the use of small passive components, reducing overall solution size.
• Includes thermal shutdown circuitry to protect the device during overload or excessive junction temperature conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring high input voltage regulation

• Battery-powered applications utilizing high-voltage battery stacks

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required package type and temperature rating. Cross-reference datasheet revisions to validate feature sets and recommended operating conditions prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed 40 V, as lower voltage variants may not withstand the potential stress. Consider the 500 mA current limit for load requirements. Evaluate thermal performance based on the SOIC package dissipation capabilities relative to the expected ambient temperature and load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2594M-ADJ but differs in maximum input voltage ratings and package options. The series is designed for high-efficiency DC-DC conversion with minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2594MX-ADJ/NOPB offers identical electrical characteristics in a smaller MSOP-8 package. LM2594N-ADJ/NOPB provides through-hole mounting alternatives. Verify pin-to-pin compatibility and thermal management requirements when substituting.
